Despite sounding similar, they are unrelated. Cancer is a serious disease in which abnormal cells grow uncontrollably, often forming tumours. A canker is a small ulcer or sore — a canker sore appears in the mouth — and in plants it means an area of dead, diseased bark. Only the spelling is close.

What are the main types of cancer?

Cancers are usually named after where they begin, such as breast, lung, skin, or bowel cancer. Doctors also group them by cell type: carcinomas start in skin or organ linings, sarcomas in bone or soft tissue, leukaemias in blood, and lymphomas in the immune system. There are more than a hundred kinds.

Can cancer be cured?

Many cancers can be treated successfully, and some are curable, especially when found early. Outcomes depend heavily on the type, stage, and the person's overall health. Common treatments include surgery, chemotherapy, radiotherapy, and newer targeted therapies. Even when a cure isn't possible, treatment can often control the disease and extend life.

What is the difference between a tumour and cancer?

A tumour is simply a lump formed by abnormal cell growth, and not all tumours are cancer. Benign tumours grow slowly, stay in one place, and are usually harmless. Malignant tumours are cancerous — they invade nearby tissue and can spread. So cancer always involves harmful growth, but a tumour may be entirely benign.
