Millions of people die every year, some in accidents, some due to strokes, some due to diabetes; but statics show that there is one major disease that tops the list second to only heart problems, i.e. Cancer.
Immunotherapy brings hope in the fight against cancer, a deadly disease
Cancer is a disease that involves abnormal cell growth which may spread to other areas of the body. The cells of the body undergo cell division infinitely forming tumours. This deadly disease alone causes millions of deaths every year. The different types of cancer include lung cancer, breast cancer, brain cancer, skin cancer, stomach cancer, prostate cancer, leukaemia, colorectal cancer, mouth cancer, cervical cancer etc.
There are two types of tumours, benign and malignant. Benign tumours are those which are not cancerous. They don’t spread to other parts of the body and in most cases are curable unless the tumours are pressing against important blood vessels. Malignant tumours, on the other hand, are cancerous tumours which have the potential to spread to other parts of the body. In these types of tumours, cells divide uncontrollably, metastasize or spread to other parts of the body and destroy tissues. The highly unstable and abnormal cells travel through the blood and lymphatic system. These tumours if not treated in the early stages may lead to death.
Cancer can develop due to various reasons. There is no single particular cause of cancer. Lung cancer is caused mainly due to smoking and tobacco. Skin cancer can be caused due to exposure to intense sunlight and radiation. Other causes include bacteria, virus, infections, poor diet and low physical activity. It can be caused due to environmental and physical conditions as well; for instance, people working in factories exposed to constant radiation have more chances for developing cancer, genetic reasons, radiation from mobile phones may cause cancer, chemicals present in hair dyes also have the potential to cause cancer.
Cancer treatment – the sooner the better. The size or progression of cancer can be described in stages. Normally, there are 4 stages of cancer. Stage one means that the cancer is relatively small and can be treated. In stage 2 cancer has grown but hasn’t yet spread widely. Stage 3 implies that a tumour is slowly starting to spread and is entering the lymph node. Stage 4 also called the metastatic or secondary stage indicates that cancer has spread to other organs. Depending on the diagnosis of cancer, the treatment is decided upon. The early stages can be treated using surgery and completely removing the tumour before it spreads. In case of later stages, chemotherapy, hormone therapy or targeted drugs may be used.
Prevention is better than cure. Would be a shame if you’ve studied for UPTU 2018 but you can’t write the exam because your health gave up on you. Cancer can be prevented by changing certain behavioural aspects. Choosing not to smoke tobacco, not consuming alcohol, regular exercise and a good diet, protecting yourself from the sun by wearing the right clothes and applying sunscreen etc. are known to reduce the risk of cancer. Diagnosis and treatment of the various types of cancer is not only emotionally and mentally draining but is also expensive; certainly more expensive than PDM University Fees and Courses offered would not be as versatile as the different types of cancers out there.
