🧬 Module 23: Cancer (Various Types)
Cancer is a group of diseases where abnormal cells grow uncontrollably and may spread to other parts of the body.
🔬 Common Types
- Breast cancer
- Lung cancer
- Prostate cancer
- Colorectal cancer
- Skin cancer (e.g. basal cell carcinoma)
- Bladder cancer
⚠️ Causes & Risk Factors
- Genetic mutations
- Smoking and tobacco exposure
- Radiation exposure
- Lifestyle factors (diet, alcohol, inactivity)
- Environmental toxins
🏥 Treatment Options
- Surgery (removal of tumour)
- Chemotherapy (drugs targeting cancer cells)
- Radiotherapy (targeted radiation)
- Immunotherapy (boosting immune response)
🧠 Key Idea
Cancer is not one disease — it is a group of conditions with different causes, behaviours, and treatments.
✋ Module 24: Carpal Tunnel Syndrome
Carpal Tunnel Syndrome happens when pressure is placed on the median nerve in the wrist.
📌 Symptoms
- Tingling in fingers
- Numbness or “pins and needles”
- Wrist or hand pain
- Weak grip strength
⚠️ Causes
- Repetitive hand movements
- Wrist strain or injury
- Diabetes
- Rheumatoid arthritis
🛠️ Treatment
- Wrist splints (especially at night)
- Anti-inflammatory medication
- Ergonomic changes (workstation adjustments)
- Surgery (in severe cases)
🧠 Key Idea
It is a nerve compression condition, often linked to repetitive strain or medical conditions.
🦠 Module 25: Cellulitis (Bacterial Skin Infection)
Cellulitis is a bacterial infection of the skin and deeper tissues.
🔴 Symptoms
- Red, swollen skin
- Warmth in affected area
- Pain or tenderness
- Rapid spreading infection
⚠️ Risk Factors
- Cuts or broken skin
- Skin conditions
- Obesity
- Lymphoedema
- Weakened immune system or cancer treatment
💊 Treatment
- Immediate antibiotics
- Hospital care if severe
- Monitoring to prevent spread to blood or deeper tissues
🚨 Key Warning
Cellulitis can become life-threatening if untreated.
🧒 Module 26: Chickenpox & Chlamydia (Infection Types)
🧒 Chickenpox (Viral Infection)
Chickenpox is a highly contagious viral infection caused by varicella-zoster virus.
📌 Symptoms
- Itchy blister-like rash
- Fever
- Fatigue
- Spots that scab over
🛡️ Prevention
- Vaccination (highly effective)
- Avoid contact with infected individuals
🧠 Key Idea
Usually mild in children, but can be more severe in adults or vulnerable people.
🧫 Chlamydia (Sexually Transmitted Infection)
Chlamydia is a common bacterial STI caused by Chlamydia trachomatis.
⚠️ Symptoms
- Often no symptoms (silent infection)
- Pain during urination
- Unusual discharge
- Pelvic or testicular pain
💊 Treatment
- Antibiotics (simple and effective)
- Early treatment prevents complications
🚨 If Untreated
- Infertility
- Pelvic inflammatory disease
- Long-term reproductive damage
🧠 Key Idea
Chlamydia is highly treatable but often unnoticed, which is why testing is important.
📊 Summary Table (Modules 23–26)

| 23 | Cancer | Cellular / systemic disease |
| 24 | Carpal Tunnel | Nerve compression (wrist) |
| 25 | Cellulitis | Skin bacterial infection |
| 26 | Chickenpox & Chlamydia | Viral + bacterial infections |
