"Big C" refers to a term commonly used to describe cancer, a group of diseases characterized by the uncontrolled growth of abnormal cells in the body. These cells can invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system. There are many types of cancer, including breast cancer, lung cancer, and prostate cancer, each with its own risk factors and treatment options. Early detection and treatment are crucial for improving outcomes in cancer patients. Common methods for diagnosing cancer include imaging tests like X-rays and MRIs, as well as biopsies to analyze tissue samples. Treatment options may involve surgery, radiation therapy, chemotherapy, or targeted therapies, depending on the type and stage of cancer.
