What are multifocal tumors?
Multifocal tumors are not multiple tumors; they originate from a unique cellular clone and grow multifocally in a single organ (liver, kidney, thyroid, etc.). These tumors are not included as multiple primary malignancies (MPM), but they can represent a single event of this syndrome.
What is multifocal pathology?
What does multifocal mean? Pathologists use the word multifocal to describe something seen in more than one part of a tissue sample. Multifocal changes can be seen when the tissue is examined by eye (this is called the gross examination) or under the microscope. Similar words include focal and diffuse.
Do cancer tumors grow and shrink?
At the same time, if a cell doesn’t divide, it also cannot grow and spread. For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).
Is it normal to have lots of lumps in your breasts?
If you feel a lump in your breast, you should always get it checked by a GP. Most breast lumps are harmless, but some can be serious.
What does multifocal mean in medical terms?

Should I worry about lumps in my breast?
If you feel a lump in your breast, try not to panic or worry. Most lumps are not breast cancer, but something less serious, such as a benign breast condition. Some lumps go away on their own. In younger women, lumps are often related to menstrual periods and go away by the end of the cycle.
What is the difference between multifocal and multicentric breast cancer?
Breast cancers were defined as multifocal (MF) if there was more than one focus of invasive breast cancer separated by benign tissue in the same quadrant, and multicentric (MC) when distinct tumour foci were found in different quadrants of the breast.
What does unifocal tumor mean?
Unifocal refers to the primary tumour having a single foci of cancer cells, and multifocal refers to the primary tumour having two or more foci of cancer cells. Definitions of focality in relation to spread are specific to the cancer site.
Can you have more than one tumor in your breast?
Multifocal breast cancer occurs when there are two or more tumors in the same breast. All of the tumors begin in one original tumor. The tumors are also all in the same quadrant — or section — of the breast. Multicentric breast cancer is a similar type of cancer.
