Antitumour

Antitumour refers to substances or treatments that are effective against tumours. Tumours are abnormal masses of tissue that can be benign or malignant. Malignant tumours, also known as cancers, have the potential to invade surrounding tissues and spread to other parts of the body. Antitumour agents work through various mechanisms to inhibit tumour growth, kill tumour cells, or prevent their spread.

These agents can be broadly classified into several categories. Chemotherapy involves the use of drugs that kill rapidly dividing cells, including cancer cells. Radiation therapy uses high-energy rays to damage or destroy cancer cells. Immunotherapy harnesses the body's own immune system to fight cancer. Targeted therapy focuses on specific molecules involved in cancer cell growth and survival. Hormone therapy is used for cancers that are sensitive to hormones, such as breast and prostate cancer.

The development and study of antitumour agents is a major focus in cancer research. Scientists work to identify new compounds and therapeutic strategies that can more effectively target cancer cells while minimizing harm to healthy tissues. This involves understanding the complex biology of cancer and developing precise methods for intervention. The effectiveness of antitumour treatments can vary depending on the type and stage of cancer, as well as individual patient factors.
