A tumor (neoplasm) is a solid mass of tissue that forms when abnormal cells group together. They can form most anywhere in your body, including your bones, skin, tissue, organs and glands. Many tumors are benign, which means they’re not cancer. You may or may not need treatment for them. Cancerous, or malignant, tumors require cancer treatment.

2021年10月11日 · Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body. Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and multiply (through a process called cell division) to form new cells as the body needs them.

A list of all cancers, organized by location and/or function in the body. Cancers on the list are linked to information about treatment, supportive care, screening, prevention, clinical trials, and other topics.

2023年11月16日 · Tumors can occur almost anywhere in the body. There are three main types of tumor; benign premalignant, and malignant. Benign and premalignant tumors can be harmless, whereas malignant...

2024年7月29日 · A tumor is an external or internal lump caused by excessive cell growth. Tumors can be cancerous (malignant), precancerous, or noncancerous (benign). Some tumors grow slowly and cause no symptoms, while others get very large and spread to other parts of the body.

2025年2月5日 · The mechanism by which a tumour brings about profound changes in host metabolism and body composition has long been discussed, especially as the tumour constitutes such a small percentage of host ...

2024年7月2日 · Throughout our lives, healthy cells in our bodies divide and replace themselves in a controlled fashion. Cancer starts when a cell is somehow altered so that it multiplies out of control. A tumor...

2023年10月27日 · In this paper, I briefly review the biological basis for a link between body composition and cancer survival and summarize the epidemiological evidence with consideration to specific exposure...

2025年1月29日 · Inflammation can also promote cancer in cells that have already mutated. PM 2.5 particles, for instance, have been shown to induce inflammation in the lungs, waking up dormant mutant cells to fuel ...
