Why are cancer sufferers offered radiotherapy and chemotherapy?

Cancer sufferers are offered radiotherapy and chemotherapy as two of the most frequently used treatments to fight cancer. Radiotherapy uses high energy radiation in order to destroy cancer cells and shrink any tumors present. This treatment has a 95% success rate when it comes to localizing the tumor, meaning that through its use, it can reduce pain and increase life spans of those affected by cancer.

Chemotherapy is also used commonly when treating cancer patients, as it is one of the few viable options for those whose cancers cannot be surgically removed. Chemotherapy involves the use of drugs which help kill off many types of rapidly growing cell lines within our bodies – such as those found in some types of cancers- while preserving other healthier cells in our body like hair follicles & healthy tissues. It also helps boost our immune systems’ ability to target these abnormal cell lines by causing them to release chemicals which mark them for destruction from an array of sources including white blood cells, antibiotics, or other substances produced from within us after therapy has been administered. With nearly 20 million people undergoing chemotherapy annually worldwide – with a reported 74% chance at achieving remission - chemo provides countless individuals with hope in their fight against this deadly disease every day!
