Cancer – Causes, Symptoms, and Treatments
Cancer is the abnormal growth of cells due to certain mutations in the DNA. It is alternatively known as malignancy and the cluster of the abnormal cells is called a tumor. Tumors are of two types—cancerous (malignant) tumors and noncancerous (benign) tumors. The benign tumors or the noncancerous tumors do not spread whereas the malignant cancerous tumors spread to other parts of the body.
