🔬 Structure and Characteristics of Cancer Cells

Cancer cells arise from normal cells that have undergone genetic and epigenetic changes, leading to uncontrolled growth and altered cellular functions. These changes affect both the internal cellular structures and behavior, contributing to the pathogenesis of malignancies.

🧬 STRUCTURAL FEATURES OF CANCER CELLS

Nucleus and Nucleolus:
- 🔹 Enlarged nucleus: Cancer cells often have a larger nucleus-to-cytoplasm (N/C) ratio than normal cells.
- 🔹 Hyperchromatism: The nuclear chromatin is densely stained due to increased DNA content.
- 🔹 Irregular nuclear membrane: The nuclear shape is distorted or lobulated.
- 🔹 Multiple and prominent nucleoli: Nucleoli may be abnormally large and visible, indicating increased protein synthesis activity.
Cytoplasm:
- 🔹 Scanty or vacuolated cytoplasm: Cytoplasmic volume is often reduced, or vacuoles may appear due to metabolic abnormalities.
- 🔹 Abnormal organelles: Mitochondria, ribosomes, and endoplasmic reticulum may be malformed or functionally altered.
Cell Membrane:
- 🔹 Altered surface markers: Cancer cells express abnormal antigens, such as tumor-associated antigens (TAA).
- 🔹 Reduced adhesion molecules: Decreased E-cadherin contributes to loss of contact inhibition and facilitates invasion and metastasis.

🧪 FUNCTIONAL & BEHAVIORAL CHARACTERISTICS OF CANCER CELLS

✅ Uncontrolled Cell Division:
- Cancer cells divide indefinitely and bypass cell cycle checkpoints.
- Mutations in genes like proto-oncogenes (e.g., RAS) and tumor suppressor genes (e.g., p53, RB) drive persistent proliferation.
⚠️ Loss of Contact Inhibition:
- Normal cells stop dividing upon touching neighboring cells.
- Cancer cells continue proliferating, forming disorganized layers or masses.
❌ Evasion of Apoptosis:
- Cancer cells avoid programmed cell death, even when DNA is damaged.
- Mutations in genes like p53 help cancer cells evade apoptosis.
🔁 Dedifferentiation and Anaplasia:
- Cancer cells lose specialized features and revert to a more primitive, undifferentiated state.
- Anaplasia is a hallmark of malignancy and correlates with aggressiveness.
🧬 Genetic Instability and Mutations:
- DNA repair mechanisms are faulty, leading to accumulation of mutations.
- Chromosomal abnormalities such as translocations, deletions, duplications, and aneuploidy are common.
🌱 Sustained Angiogenesis:
- Cancer cells stimulate new blood vessel formation by secreting vascular endothelial growth factor (VEGF).
- This provides oxygen and nutrients for tumor growth and survival.
🌍 Invasion and Metastasis:
- Cancer cells secrete proteolytic enzymes (e.g., matrix metalloproteinases) that degrade the extracellular matrix.
- They migrate through tissues, enter the bloodstream or lymphatics, and colonize distant organs.
⚡ Abnormal Energy Metabolism (Warburg Effect):
- Prefer aerobic glycolysis even in the presence of oxygen.
- Increases glucose uptake and lactic acid production, supporting rapid proliferation.
🛡️ Immune Evasion:
- Cancer cells may downregulate MHC molecules, secrete immunosuppressive cytokines, or express immune checkpoint ligands (e.g., PD-L1) to evade immune detection.
🧪 Autocrine Growth Stimulation:
- Cancer cells often secrete growth factors that bind to their own receptors, promoting self-stimulation.

📚 Summary of Hallmarks of Cancer (Hanahan & Weinberg, 2011)

Cancer cells are defined by several core capabilities:

Sustained proliferative signaling
Evading growth suppressors
Resisting cell death
Enabling replicative immortality
Inducing angiogenesis
Activating invasion and metastasis
Genome instability and mutation
Tumor-promoting inflammation
Deregulating cellular energetics
Avoiding immune destruction

📌 Conclusion

Cancer cells represent a breakdown of normal cellular regulation. Their structure is distorted, and they behave in a malignant manner — proliferating uncontrollably, evading death, and spreading to new sites. Understanding these characteristics is crucial for the diagnosis, classification, and treatment of various cancers.

🧬 ETIOLOGY OF CANCER

Etiology refers to the causes or factors responsible for the development of cancer. Cancer is multifactorial, arising from the interaction of genetic susceptibility and environmental or lifestyle factors that lead to uncontrolled cell growth and malignancy.

🔍 I. CLASSIFICATION OF CANCER ETIOLOGY

🔸 A. Environmental and Lifestyle Factors (Exogenous)

These are external factors that contribute to DNA damage and mutation.

1. 🚬 Tobacco and Smoking

Leading cause of lung, oral, esophageal, laryngeal, and bladder cancers
Contains carcinogens like benzopyrene, nitrosamines, and arsenic

2. 🍺 Alcohol Consumption

Increases risk of liver, breast, oral, esophageal, and colorectal cancers
Acts synergistically with tobacco

3. 🍟 Diet and Obesity

High-fat, low-fiber diet linked to colorectal, breast, and prostate cancers
Obesity is associated with endometrial, pancreatic, and gallbladder cancers

4. ☀️ Radiation Exposure

Ultraviolet (UV) radiation: Skin cancer, including melanoma
Ionizing radiation: Leukemia, thyroid, breast cancers (e.g., radiation therapy or nuclear accidents)

5. ☣️ Chemical Carcinogens

Asbestos → Mesothelioma
Aflatoxins (from moldy food) → Liver cancer
Arsenic, vinyl chloride, formaldehyde, dyes → Skin, liver, bladder cancers

6. 🦠 Infections (Oncogenic Pathogens)

🦠 Agent	📌 Cancer Type
HPV (Human Papillomavirus)	Cervical, anal, oropharyngeal cancers
HBV/HCV (Hepatitis B/C viruses)	Liver cancer
EBV (Epstein-Barr Virus)	Burkitt’s lymphoma, nasopharyngeal carcinoma
H. pylori (bacteria)	Stomach cancer
HIV	Kaposi sarcoma, Non-Hodgkin lymphoma

7. ⚠️ Occupational Exposures

Factory or lab workers exposed to chemicals, radiation, asbestos
Linked to lung, bladder, and skin cancers

🔸 B. Genetic and Biological Factors (Endogenous)

These are internal or inherited influences that make some individuals more susceptible.

1. 🧬 Genetic Mutations

Activation of oncogenes (e.g., RAS, MYC)
Inactivation of tumor suppressor genes (e.g., TP53, RB)

2. 👨‍👩‍👧‍👦 Hereditary Syndromes

👨‍👩‍👧‍👦 Syndrome	🧪 Cancers
BRCA1/2 mutations	Breast & ovarian cancer
Lynch syndrome (HNPCC)	Colorectal, endometrial cancer
Li-Fraumeni syndrome	Multiple cancers (early onset)

3. 🔁 Hormonal Imbalance

Estrogen excess: Breast, endometrial cancers
Androgen: Prostate cancer

4. ⏳ Age and Gender

Increased age = higher risk due to cumulative mutations
Some cancers are gender-specific (e.g., prostate, cervical)

🔬 II. MOLECULAR MECHANISM BEHIND CANCER ETIOLOGY

DNA Damage
- Mutations occur in genes that regulate cell growth and apoptosis
- Caused by chemicals, radiation, or errors during cell division
Failure of DNA Repair Mechanisms
- Mutated cells continue to survive and multiply
Oncogene Activation & Tumor Suppressor Gene Inactivation
- Leads to uncontrolled cell division, evasion of apoptosis
Angiogenesis and Metastasis
- Cancer cells stimulate new blood vessels and invade other tissues

📌 III. INTERACTION BETWEEN ENVIRONMENT & GENES

Most cancers arise from a complex interaction between environmental exposures and individual genetic susceptibility. For example:

A smoker with a p53 mutation has a higher lung cancer risk.
A woman with BRCA mutation exposed to estrogen for a long time has higher breast cancer risk.

🌟 SUMMARY: ETIOLOGY OF CANCER

🔠 Category	🔍 Examples
Lifestyle	Smoking, alcohol, diet, obesity, inactivity
Environmental	Radiation, chemicals, pollution, occupational hazards
Infections	HPV, HBV, HCV, EBV, H. pylori, HIV
Genetic	Mutations (oncogenes, tumor suppressor genes), hereditary syndromes
Biological	Age, sex, hormones, immune suppression

✅ Key Points to Remember:

Cancer is multifactorial: both internal and external factors contribute.
Preventable causes like tobacco and infection account for >50% of cancer cases.
Understanding etiology is vital for prevention, early detection, and treatment planning.

🧬 CLASSIFICATION OF CANCER

Cancer (or malignancy) refers to the abnormal and uncontrolled proliferation of cells that can invade surrounding tissues and spread to distant sites. For diagnosis, treatment planning, and prognosis, cancer is classified based on origin, cell type, behavior, and spread.

📘 I. CLASSIFICATION BASED ON CELL/TISSUE OF ORIGIN

This is the most common and clinically relevant classification.

🔹 1. Carcinoma (∼90% of cancers)

Originates from epithelial cells
Can affect skin, glands, and mucous membranes
Subtypes:
- Adenocarcinoma – from glandular epithelium (e.g., breast, colon, prostate)
- Squamous cell carcinoma – from squamous epithelium (e.g., skin, cervix, lungs)

🔹 2. Sarcoma

Arises from connective or supportive tissues
Includes bone, cartilage, fat, muscle, blood vessels
Examples:
- Osteosarcoma (bone)
- Chondrosarcoma (cartilage)
- Liposarcoma (fat)
- Leiomyosarcoma (smooth muscle)

🔹 3. Leukemia

Originates in the bone marrow and affects white blood cells
No solid tumors; found in blood and marrow
Types:
- Acute lymphoblastic leukemia (ALL)
- Chronic myeloid leukemia (CML)

🔹 4. Lymphoma

Originates in lymphatic system
Solid tumors of immune cells
Two major types:
- Hodgkin lymphoma (HL)
- Non-Hodgkin lymphoma (NHL)

🔹 5. Myeloma

Cancer of plasma cells in bone marrow
Example: Multiple myeloma

🔹 6. Melanoma

Arises from melanocytes (pigment-producing cells in skin)
Highly aggressive
Can also occur in the eye or mucous membranes

📘 II. CLASSIFICATION BASED ON HISTOLOGICAL FEATURES

🔸 Well-differentiated:

Cells resemble normal cells; grow slower
Better prognosis

🔸 Poorly differentiated / Undifferentiated:

Cells look very abnormal; grow and spread faster
Worse prognosis

📘 III. CLASSIFICATION BASED ON BEHAVIOR

🔹 Type	🔍 Definition
Benign Tumors	Non-cancerous, localized, slow-growing, do not metastasize
Malignant Tumors	Cancerous, invasive, fast-growing, may metastasize
In situ carcinoma	Localized pre-cancerous lesion; has not invaded surrounding tissues

📘 IV. CLASSIFICATION BASED ON ANATOMICAL SITE (Organ System)

🧬 PATHOPHYSIOLOGY OF CANCER

Cancer is a group of diseases characterized by uncontrolled cell division, loss of differentiation, invasion of surrounding tissues, and potential to metastasize to distant organs. It results from a multistep process involving genetic mutations and molecular alterations in normal cells.

🧠 NORMAL CELL GROWTH VS. CANCEROUS GROWTH

🔹 Normal Cells	💢 Cancer Cells
Controlled by growth signals	Grow without regulation
Undergo apoptosis if damaged	Evade apoptosis and survive
Have contact inhibition	Grow over each other and invade
Limited number of divisions	Divide indefinitely

🔄 STEPS IN CANCER PATHOGENESIS

🔸 1. Initiation (Genetic Mutation)

A normal cell undergoes irreversible genetic changes due to exposure to:
- Carcinogens (tobacco, UV light, chemicals)
- Radiation
- Oncogenic viruses (e.g., HPV, EBV)
DNA damage affects proto-oncogenes, tumor suppressor genes, or DNA repair genes.

🔬 Example: Mutation in TP53 (tumor suppressor gene) disrupts apoptosis.

🔸 2. Promotion (Clonal Expansion)

The mutated cell begins to proliferate abnormally.
Influenced by growth factors, hormones, chronic inflammation, etc.
The cells escape normal regulation and expand clonally.

📌 No structural change yet, but functionally pre-cancerous.

🔸 3. Progression (Malignant Transformation)

The abnormal cells acquire more mutations, becoming invasive and malignant.
Hallmarks:
- Uncontrolled proliferation
- Loss of differentiation (anaplasia)
- Immortality (via telomerase activation)
- Invasion of surrounding tissues
- Angiogenesis (new blood vessel formation)
- Metastasis (spreading via blood or lymph)

🧬 Cancer becomes clinically detectable in this stage.

🔬 MOLECULAR BASIS OF CANCER DEVELOPMENT

🔹 A. Oncogene Activation

Proto-oncogenes (normal) → oncogenes (mutated) → promote cell growth and division
Examples: RAS, MYC, HER2

🔹 B. Inactivation of Tumor Suppressor Genes

Genes that suppress growth become mutated/inactive
Examples: TP53, RB1, APC

🔹 C. Failure of DNA Repair Mechanisms

Defective DNA repair → accumulation of mutations
Example: BRCA1/2 mutations in breast and ovarian cancer

🌱 ANGIOGENESIS IN CANCER

Tumor cells release VEGF (Vascular Endothelial Growth Factor)
→ stimulates new blood vessel formation
→ supplies nutrients and oxygen
→ enables tumor growth and metastasis.

🌍 METASTASIS: SPREAD OF CANCER

🔄 Steps of Metastasis
1. Invasion of basement membrane
2. Intravasation into blood/lymph
3. Survival in circulation
4. Extravasation into new tissue
5. Colonization and secondary tumor formation

🧠 Common metastatic sites:

Bone (prostate, breast)
Liver (colon)
Lungs (kidney, breast)
Brain (lung, breast, melanoma)

⚠️ HALLMARKS OF CANCER (Hanahan & Weinberg)

Self-sufficiency in growth signals
Insensitivity to anti-growth signals
Evasion of apoptosis
Limitless replicative potential (immortality)
Sustained angiogenesis
Tissue invasion and metastasis
Genomic instability
Inflammation-promoted growth
Deregulated metabolism
Immune system evasion

📌 SUMMARY: PATHOPHYSIOLOGY OF CANCER

🔠 Stage	🔍 Description
Initiation	DNA mutation due to carcinogens or radiation
Promotion	Mutated cells divide abnormally and form a mass
Progression	Further mutations → invasion, metastasis
Molecular Basis	Involves activation of oncogenes, loss of tumor suppressor genes, angiogenesis, and immune evasion
Clinical Result	Formation of detectable tumor with systemic effects like weight loss, fatigue, and metastasis

🎯 STAGING OF CANCER

🔬 What is Cancer Staging?

Staging refers to the process of determining the extent or spread of cancer in the body. It is crucial for:

📌 Choosing the most appropriate treatment
📈 Estimating prognosis
🔁 Comparing results of treatment among different patients
🧾 Documenting cancer progression over time

🧠 I. THE TNM STAGING SYSTEM (Developed by AJCC/UICC)

The TNM system is the most widely used cancer staging classification. It is based on:

🔠 Component	🧾 Meaning
T (Tumor)	Size and extent of the primary tumor
N (Node)	Spread to regional lymph nodes
M (Metastasis)	Distant metastasis (spread to other organs)

🔹 T – Primary Tumor Size and Invasion

T Category	Description
T0	No evidence of primary tumor
Tis	Carcinoma in situ (localized, non-invasive)
T1–T4	Increasing size and/or extent of invasion

🔹 N – Regional Lymph Node Involvement

N Category	Description
N0	No lymph node involvement
N1–N3	Increasing number and/or size of lymph nodes involved

🔹 M – Distant Metastasis

M Category	Description
M0	No distant metastasis
M1	Distant metastasis present

🧾 Example:

T2 N1 M0
→ Tumor of moderate size, spread to nearby lymph node(s), no distant metastasis

🩺 II. GROUP STAGING (STAGE I–IV)

Based on the TNM categories, cancers are often grouped into stages I to IV for clinical communication.

🎯 Stage	🔍 Description
Stage 0	Carcinoma in situ (pre-invasive)
Stage I	Localized cancer, small tumor, no node involvement
Stage II	Larger tumor, may have nearby node involvement
Stage III	Locally advanced, extensive node involvement
Stage IV	Distant metastasis (advanced disease)

🧪 III. OTHER STAGING METHODS

🔸 A. Clinical Staging (cTNM)

Based on physical exam, imaging (CT, MRI, PET), biopsies before treatment

🔸 B. Pathological Staging (pTNM)

Based on surgical findings and histopathology after tumor removal

🔸 C. Restaging

Done when cancer recurs or progresses after initial treatment

📊 IV. STAGING EXAMPLES BY CANCER TYPE

🧬 Cancer Type	📌 Special Staging Notes
Breast Cancer	Includes hormone receptor and HER2 status (TNM + molecular classification)
Cervical Cancer	FIGO staging (International Federation of Gynecology & Obstetrics)
Leukemia	Not staged with TNM; classified by cell type and progression (acute/chronic)
Lymphoma	Ann Arbor staging used (I to IV, based on lymph node spread)

🩺 V. NURSING IMPLICATIONS IN CANCER STAGING

✅ Area	💡 Nurse’s Role

T	Size/extent of primary tumor
N	Regional lymph node involvement
M	Presence of distant metastasis

🩺 Stage 0–IV helps describe the severity:

Stage 0 = in situ (pre-invasive)
Stage I–II = localized or early spread
Stage III = advanced local spread
Stage IV = distant metastasis

💊 CHEMOTHERAPY.

📘 I. DEFINITION

Chemotherapy is the use of cytotoxic drugs to destroy cancer cells by interfering with cell division and growth. It targets rapidly dividing cells, including malignant cells — but also affects some healthy tissues.

🎯 II. GOALS OF CHEMOTHERAPY

🎯 Goal	📋 Description
Curative	Complete eradication of cancer (e.g., testicular cancer, lymphoma)
Control	Shrinking or halting tumor progression (e.g., breast, ovarian cancer)
Palliative	Relief of symptoms and improved quality of life (e.g., advanced cancer)
Adjuvant	After surgery/radiation to kill residual cells
Neoadjuvant	Before surgery to shrink tumor size

🧬 III. CLASSIFICATION OF CHEMOTHERAPEUTIC DRUGS

🧪 Drug Class	📋 Mechanism of Action	💉 Examples
Alkylating agents	Damage DNA	Cyclophosphamide, Ifosfamide
Antimetabolites	Mimic normal cell metabolites → block DNA synthesis	Methotrexate, 5-Fluorouracil
Antitumor antibiotics	Bind to DNA → inhibit replication	Doxorubicin, Bleomycin
Plant alkaloids	Inhibit mitosis (cell division)	Vincristine, Paclitaxel
Topoisomerase inhibitors	Interfere with enzymes for DNA replication	Irinotecan, Etoposide
Hormonal agents	Alter hormone environment	Tamoxifen (breast), Leuprolide (prostate)
Targeted therapy	Blocks specific molecules (e.g., EGFR, HER2)	Imatinib, Trastuzumab
Immunotherapy	Boost immune system to fight cancer	Nivolumab, Pembrolizumab

💉 IV. ROUTES OF ADMINISTRATION

💉 Route	📋 Used For
Intravenous (IV)	Most common; bolus, infusion, or via port
Oral	Convenient for long-term use (e.g., Capecitabine)

☢️ RADIOTHERAPY.

📘 I. DEFINITION

Radiotherapy (also known as radiation therapy) is a cancer treatment that uses high-energy ionizing radiation to destroy cancer cells by damaging their DNA. It can be used alone or in combination with surgery, chemotherapy, or immunotherapy.

🎯 II. GOALS OF RADIOTHERAPY

✅ Goal	📋 Explanation
Curative	Eradicate the tumor (e.g., head & neck cancers, prostate cancer)
Adjuvant	After surgery to destroy microscopic residual disease
Neoadjuvant	Before surgery to shrink tumor size
Palliative	Relieve symptoms in advanced cancer (e.g., bone pain, brain metastases)

🔬 III. TYPES OF RADIOTHERAPY

🔹 1. External Beam Radiotherapy (EBRT)

Most commonly used form
Radiation delivered from outside the body using a linear accelerator
Includes:
- 3D Conformal Radiation Therapy (3D-CRT)
- Intensity-Modulated Radiation Therapy (IMRT)
- Stereotactic Radiosurgery (SRS) – for brain tumors
- Stereotactic Body Radiation Therapy (SBRT) – for lung, liver

🔹 2. Internal Radiotherapy (Brachytherapy)

Radioactive sources are placed inside or near the tumor
Common in cervical, uterine, prostate, and breast cancers
Types:
- Intracavitary (e.g., vaginal or uterine)
- Interstitial (e.g., prostate seeds)
- High-Dose Rate (HDR) or Low-Dose Rate (LDR)

🔹 3. Systemic Radiotherapy

Radioactive isotopes are administered orally or intravenously
E.g., Iodine-131 for thyroid cancer, Radium-223 for bone metastases

⚙️ IV. MECHANISM OF ACTION

Radiation damages the DNA of cancer cells either directly or indirectly through ionization of water molecules, producing free radicals. Since cancer cells divide faster and have less repair ability than normal cells, they are more vulnerable to radiation.

Radiation therapy (RT) uses high-energy ionizing radiation to kill or damage cancer cells. It targets DNA within cells, preventing them from replicating or causing them to die. It can be curative, adjuvant, neoadjuvant, or palliative depending on the stage and type of cancer.

🧬 II. PRINCIPLE OF ACTION

Radiation works by damaging the DNA of rapidly dividing cancer cells, either directly or indirectly. This damage prevents the cancer cell from dividing and eventually leads to cell death through apoptosis, mitotic death, or senescence.

⚙️ III. TYPES OF MECHANISMS

🔹 1. Direct DNA Damage

Radiation particles (e.g., X-rays, gamma rays, protons) directly strike DNA molecules
Causes single-strand and double-strand breaks
Affects nucleotides in the DNA → disrupts replication and transcription

🔹 2. Indirect DNA Damage (via Free Radicals)

Radiation interacts with water molecules (H₂O) in the cell cytoplasm
Forms free radicals (like hydroxyl radical OH•)
These free radicals then attack DNA, leading to:
- Base alterations
- Strand breaks
- Crosslinking of DNA

✅ Cancer cells are more sensitive to radiation due to:

Rapid division
Less efficient DNA repair
Poor oxygen supply (hypoxia) → although hypoxic cells may resist some types of radiation

🔬 IV. PHASES OF RADIATION DAMAGE

🔠 Phase	📋 Process
Physical	Radiation energy deposited in tissue within picoseconds
Chemical	Formation of free radicals (milliseconds)
Biological	DNA damage leads to cell cycle arrest, mutation, or death over hours to days

📊 V. TYPES OF CELL DEATH CAUSED BY RADIATION

💀 Type of Death	📋 Explanation
Apoptosis	Programmed cell death; common in lymphoid tumors
Mitotic catastrophe	Cell attempts to divide with damaged DNA → fails
Senescence	Cell stops dividing permanently
Necrosis	Less common; unplanned cell death due to high doses

⚡ VI. RADIATION & THE CELL CYCLE

Radiation is most effective during:

G2 and M phases (when DNA is exposed and vulnerable)

It is less effective during:

S phase, due to DNA repair mechanisms being active

🔄 VII. FRACTIONATION CONCEPT

Radiation is given in fractions (daily small doses) to:
- Allow normal cells to repair
- Exploit differences in cell cycle timing
- Minimize late effects and toxicity

🧠 VIII. SUMMARY: RADIATION THERAPY MECHANISM

🔠 Aspect	📋 Details
Target	Cellular DNA of cancer cells
Direct damage	Ionizing radiation breaks DNA strands
Indirect damage	Free radicals from water attack DNA
Outcome	Apoptosis, mitotic death, senescence
Phases affected	G2 & M most sensitive
Cell specificity	Rapidly dividing, poorly repairing cells more affected

📚 KEY POINTS FOR NURSING & ACADEMIC USE

✅ Radiation causes DNA damage leading to cancer cell death
✅ Works via direct ionization or indirect (free radical) pathways
✅ Healthy tissues have better DNA repair, allowing recovery
✅ Delivered in fractions to balance efficacy and safety
✅ Most effective on actively dividing cells
