Do different cancers act differently?
Cancer cells are “born” when abnormal changes in DNA tell cells to grow faster and behave differently than they should. As these cancer cells multiply to form a tumor, they continue to change — becoming more and more different from each other.
What do all cancers have in common?
In fact, there are more than 100 types of diseases known collectively as cancer. What they all have in common is the overgrowth of cells, tiny units that make up all living things. Cancer (also known as malignancy, pronounced: muh-LIG-nun-see) occurs when cells begin to grow and multiply in an uncontrolled way.
Are all cancers aggressive?
It has been established that not all cancer cells are equally aggressive. Most can be neutralized with radiation and chemotherapy. Researchers have now discovered that some cancer cells can accumulate fat droplets, which appear to make them more aggressive and increase their ability to spread.
Are all cancers carcinomas?
Not all cancers are carcinoma. Other types of cancer that aren’t carcinomas invade the body in different ways. Those cancers begin in other types of tissue, such as: Bone.
How do most cancers arise?
Genetic changes that cause cancer can be inherited or arise from certain environmental exposures. Genetic changes can also happen because of errors that occur as cells divide. Most often, cancer-causing genetic changes accumulate slowly as a person ages, leading to a higher risk of cancer later in life.
What do malignant tumors look like?
Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.
What is in a tumor?
Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place.
