Cancer is the leading cause of morbidity and mortality in the world. Diagnosis of cancer causes a lot of fear, anxiety, and psychological stress for patients. A lot of misinformation is spread by myths and misconceptions about cancer. Everyone around a cancer patient becomes an adviser. Cancer myths range from etiology, diagnosis to treatment. This can contribute to delay in diagnosis and proper treatment of cancer. This causes stigma and taboo about cancer. Patient education and clarification of myths about cancer is important for cancer treatment and achieving optimal survival outcomes.
Following are a few of the common myths and their facts:
