Cancer is a genetic disease triggered by an increase in DNA mutations and epigenetic alterations that leads to uncontrolled cell proliferation and neoplasm formation. Mutation occurs frequently in the body of human, but still can be controlled. So, it won’t be possible to cause cancer with one mutation. Generally, it takes numerous mutations in the lifetime of a human to cause cancer. This is the reason older people have cancer, as they have had multiple chances for mutations. Oncogenomics deals with the characterization of cancer- associated genes. Tumor suppressor genes or oncogenes are the ones that manage the cell cycle process, hence they are called the Protective cells. These genetic changes escalate the risk of cancer. The presence of mutated genes in germ cells can be inherited to the off springs. Cancer Pharmacology deals with studying the action of drugs on cancer patients. Cancer science meetings explore new ideas and techniques for cancer therapy.
