Question

Cancer is a disease where cells in the body grow and multiply too much and too fast. This happens when a cell’s DNA changes. DNA is a molecule in every cell of all organisms. Usually, DNA gives precise instructions to cells on when to grow and repair themselves. But if DNA is damaged, it can cause too much cell growth. It may also be unable to fix errors that occur in the cells. This can cause cancer. How Cancer Develops and Spreads These cancer cells often clump together, forming a lump called a tumor. Tumors can appear anywhere in the body, such as in the liver or esophagus. Cancer cells can spread from the original tumor to other body areas. As a result, new tumors form. This spreading is known as metastasis. Genetic Links and Risk Factors for Cancer Scientists have learned that parents can pass down some DNA mutations that cause cancer. However, just inheriting these changes doesn't mean someone will definitely get cancer. The risk of cancer increases if more mutations happen in the DNA as time goes on. Other factors that can raise the risk of cancer include age, being near dangerous materials for long periods of time, too much sun exposure, and having other existing health issues. Cancer Treatment Options There are many ways to treat cancer. The treatment depends on the type of cancer, its stage, and the patient's overall health. Treatments for cancer include surgery to remove tumors, chemotherapy with drugs to kill cancer cells, and radiation therapy using strong laser beams. Another treatment called immunotherapy helps the immune system fight cancer just like it fights infections. Targeted therapy attacks specific proteins in cancer cells. Scientists are working to find even more treatments as they learn more about cancer. Which detail from the text best summarizes its central idea? A “But if DNA is damaged, it can cause too much cell growth or not be able to fix errors in the cells.” B “This spreading is known as metastasis.” C “However, just inheriting these changes doesn't mean someone will definitely get cancer.” D “A newer treatment, immunotherapy, helps the immune system fight cancer like it fights infections.”
