The Seven Warning Signs of Cancer and How Biopsy Works

The same principle applies: go for screening, be aware of the warning signs, and maintain a healthy lifestyle - regular exercise, no tobacco, minimal alcohol and a balanced diet. Doing these things means you will either not develop cancer or you will catch it early.

Chemotherapy, if not handled properly, can be toxic to people nearby. It has to be prepared in a specific mixing unit with proper precautions, and only staff trained in handling and administering chemotherapy should give it.

It is not a one-size-fits-all approach. It depends on the individual patient, which cancer is present in the body, and which site it has metastasised to. Treatment can be chemotherapy, immunotherapy or targeted therapy depending on exactly what is being treated.

Brain tumours relapse mainly if they are high-grade or advanced-stage. Complete surgical removal of a brain tumour is nearly impossible, so high-grade or advanced tumours are more likely to recur; patients with low-grade tumours tend to be cured.

Any discharge from a male breast is not normal - it can be an infection, a malignancy, or something arising from the chest wall. The key next step is imaging and a histopathological diagnosis; this could turn out to be breast cancer, which would need immediate treatment.

Change in bowel/bladder habits, a non-healing sore, unusual bleeding or discharge, a lump or thickening, difficulty swallowing, a changing wart or mole, and a persistent cough/hoarseness over four weeks.

No - this is a myth. Biopsy is the standard, necessary way cancer is diagnosed and does not accelerate spread.
