There are too many forms of cancer to name them all. However, I would like to talk about the most common types of cancer. The more you know about cancer, the better equipped you are to prevent it, fight it, and beat it if you are ever diagnosed with the big “C” word. Cancer arises from the transformation of normal cells into tumour cells in a multistage process that generally progresses from a pre-cancerous lesion to a malignant tumour. All types of cancer share common markers and cancer cells have some special characteristics including damaged cells, rapid multiplication, and the ability to spread throughout the body. The specific form of cancer is named and categorized according to the tissue area affected. The causes of cancer are still unknown. Tobacco use, alcohol use, unhealthy diet, and physical inactivity are major cancer risk factors worldwide. Long term chronic stress and emotional trauma cause cancer to grow and spread in many ways. A correct cancer diagnosis is essential for adequate and effective treatment because every cancer type requires a specific treatment regimen that encompasses one or more modalities such as surgery, radiotherapy, and chemotherapy. Palliative care is treatment to relieve, rather than cure, symptoms caused by cancer and improve the quality of life of patients and their families. Palliative care can help people live more comfortably. Diagnosed with cancer cause an immediate reaction of sadness and anger. But we must cope with those feelings.
