KES – Kenyan ShillingCancer is one of the most feared diseases worldwide — but with early detection and modern treatment, survival rates today are far better than they have ever been. Cancer can affect almost any part of the body, and it often grows silently in the early stages. That is why awareness of early warning signs and regular health screening are critically important.
This guide covers the most common types of cancer, early warning signs, causes and risk factors, how cancer is diagnosed, treatment options, and practical prevention tips — explained clearly so you can take action early.

What is Cancer?
Cancer occurs when the body's cells grow uncontrollably and form abnormal masses or tumours that can spread to other parts of the body. Common types include:
The most common cancer in women globally. Highly treatable with excellent survival rates when detected early.
Strongly linked to smoking. Often diagnosed at later stages due to few early symptoms — making awareness crucial.
Highly preventable with regular colonoscopy screening. Diet and lifestyle factors play a major role.
Leukemia, lymphoma, and myeloma affect blood cells and bone marrow. Many respond well to immunotherapy and targeted treatments.
Cervical cancer is largely preventable through HPV vaccination and regular Pap smears. Ovarian cancer needs vigilant monitoring.
Early Signs & Symptoms of Cancer
If you notice any of these symptoms persisting for more than two weeks, consult a doctor immediately:
General Warning Signs
- Unexplained weight loss
- Constant fatigue or persistent weakness
- Persistent cough or hoarseness of voice
- A lump or swelling that does not go away
Additional Red Flags
- Changes in skin colour or texture, unusual moles
- Unusual bleeding (coughing blood, rectal bleeding)
- Difficulty swallowing or persistent indigestion
- Non-healing wounds or sores that linger for weeks

Causes & Risk Factors
Cancer risk is increased by a combination of lifestyle, genetic, and environmental factors:
The single largest preventable cause of cancer — responsible for lung, throat, mouth, oesophageal, and bladder cancers.
Heavy alcohol use increases liver and breast cancer risk. Obesity is linked to cancers of the colon, breast, uterus, and oesophagus.
HPV causes cervical and head/neck cancers. Hepatitis B and C increase liver cancer risk. H. pylori is linked to stomach cancer.
BRCA gene mutations increase breast and ovarian cancer risk. Familial colon cancer syndromes (Lynch syndrome) also run in families.
Prolonged exposure to ionising radiation, asbestos, benzene, pesticides, and UV radiation from the sun significantly raises cancer risk.
Diagnosis of Cancer
Doctors use a range of advanced tests to detect and stage cancer accurately:
| Diagnostic Test | What It Detects |
|---|---|
| Blood Tests & Tumour Markers | Cancer-specific proteins (PSA, CA-125, CEA) in the bloodstream |
| Biopsy | Microscopic examination of cells to confirm cancer type |
| CT Scan / MRI | Tumour size, location, and spread to nearby structures |
| PET Scan | Metabolic activity and cancer spread throughout the body |
| Endoscopy / Colonoscopy | Internal examination for digestive tract cancers |
| Mammography | Early detection of breast cancer in women |
Treatment Options for Cancer
Cancer treatment depends on the type, stage, and overall health of the patient. Modern oncology offers a wide range of effective options:
Removal of tumours — from minimally invasive laparoscopic surgery to robotic-assisted procedures at leading cancer centres.
Powerful drugs that kill rapidly dividing cancer cells throughout the body. Used alone or in combination with other treatments.
High-energy rays precisely targeted at tumours. Advanced techniques like IMRT and proton therapy minimise damage to surrounding tissue.
Harnesses the body's immune system to recognise and destroy cancer cells. Checkpoint inhibitors have revolutionised cancer treatment.
Precision medicines that attack specific genetic mutations or proteins driving cancer growth — with fewer side effects than chemotherapy.
Used for blood cancers — replaces diseased bone marrow with healthy blood-forming stem cells. Available at specialist centres in India.
Cancer Prevention Tips
Up to 40% of all cancers can be prevented through healthy lifestyle choices and regular screening:
Lifestyle Prevention
- Quit smoking and avoid all tobacco products
- Limit alcohol — no more than 1–2 units per day
- Eat a diet rich in fruits, vegetables, and fibre
- Maintain a healthy weight and exercise regularly
Screening & Vaccination
- Get vaccinated for HPV (prevents cervical cancer) and Hepatitis B
- Regular screening: mammogram after 40, colonoscopy after 45
- Know your family history — discuss genetic screening with a doctor
- Protect yourself from excessive UV exposure (sunscreen, shade)
Frequently Asked Questions
Breast cancer, prostate cancer, thyroid cancer, and skin cancers (basal cell and squamous cell) have high survival rates when diagnosed at an early stage. Testicular cancer also has a very high cure rate even at advanced stages.
Yes — research shows that up to 40% of cancers can be prevented by avoiding smoking, eating a healthy diet, maintaining a healthy weight, limiting alcohol, exercising regularly, and getting relevant vaccinations.
No — many cancers are treatable and even curable when diagnosed early. Modern treatments including immunotherapy, targeted therapy, and precision surgery have dramatically improved survival rates across most cancer types.
After age 40, regular annual or biannual screening is recommended — particularly for breast, cervical, colon, and prostate cancers. Those with a family history of cancer should start screening earlier. Discuss with your doctor based on your risk profile.
Conclusion
Cancer awareness truly saves lives. Early detection remains the most powerful weapon against cancer — many cancers detected early have cure rates above 90%. Don't ignore persistent symptoms. Regular screening, healthy habits, and expert medical guidance are your best defences.
