Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

What is the frequency of benign colon tumors compared to cancerous tumors?

What is the frequency of benign colon tumors compared to cancerous tumors?

Small and about 5%: Other than for congenital polyposis the majority of lesions arise in a field effect initiated by the polyoma virus. Contrary to the belief that adenomatous polyps convert to malignant polyps and then Ca this occurs in about 5 % of pts. 95% arise from premalignant cells in the viral or carcinogen field. ...Read more

Can a large polyp in your colon mean colon cancer?

Is an spts tumor in the pancreas cancerous?

Is an spts tumor in the pancreas cancerous?

Fatty infiltration: Fatty infiltration is just what it sounds like - excess fat within and around the pancreas. This condition is benign (not harmful, not cancerous) in the sense that it does not disrupt the normal pancreatic functions of making hormones and making digestive enzymes, plus it does not increase the risk of pancreatic cancer. If a person has fatty infiltration due to obesity, he should lose some weight. ...Read more

Can a benign tumor metastasize?

Can a benign tumor metastasize?

No.: By definition, a benign tumor does not metastasize (spread to other sites by invading the blood stream or lymphatic system). Extremely rare cases of 'parasitic' or implanted benign tumors (eg leiomyomas of the uterus) are recognized to occur in sites outside their normal origin, but this is thought to be a result of some form of tissue transplantation, and not true tumor ''metastasis' ...Read more

Will a fibroadenoma benign tumor in my breast become malignant?

Will a fibroadenoma benign tumor in my breast become malignant?

No: Fibroadenomas are the most common breast tumor. Excision is not necessary unless there are features that would suggest a rare variant of fibroadenomas, called phyllodes tumors. Despite this, some women will still opt for excision due to the size of the tumor and/or fear surrounding constantly feeling a lump in one's breast. If reassurance fails, the surgery itself is quite minimal. ...Read more

Could a noncancerous lung tumor turn cancerous without warning?

Could a noncancerous lung tumor turn cancerous without warning?

Only certain types: Some noncancerous lung tumors are benign and will always remain benign. Other noncancerous tumors, such as bronchoalveolar carcinomas (now called carcinoma in-situ) can become cancerous tumors. ...Read more

Are small sessile colon polyps usually cancerous?

Are small sessile colon polyps usually cancerous?

No ...: ... On the contrary. The smaller the polyp, the less likely it is to be "cancerous". Sessile just means flat (harder to find) versus pedunculated (mushroom-shaped). The precancerous type of polyps are adenomatous and serrated polyps (documented on pathology). Hyperplastic polyps in general are almost always benign and never turn into cancer. ...Read more

What are sessile polyps found in colon sent to pathology?

What are sessile polyps found in colon sent to pathology?

Flat polyps: Sessile refers to the morphology of the polyp rather than the polyp type. Sessile polyps are more flat than peduculated polyps, which grow from a stalk. Once removed, the polyp is sent to pathology to determine the polyp type (hyperplastic, adenoma, cancer, etc). ...Read more

Does colon cancer cause abscess in the colon?

Does colon cancer cause abscess in the colon?

It can: If the cancer perforates the wall of the colon allowing feces to spill into localized area, an abscess can form. This more commonly happens with diverticulitis but can happen with cancer as well. ...Read more

Are colon polyps cancerous?

Are colon polyps cancerous?

Some: There are different types of colon polyps. Some will not turn into cancer. But many (adenomatous polyps in particular) have a high likelihood of turning into cancer if not removed. We think that most colon cancers start as polyps. That is why we recommend colonoscopy at age 50. If you have a precancerous polyp, it can be removed before you get cancer. ...Read more

Colon biopsy:huge tubulovillous adenoma with marked atypia, multi foci adenocarcinoma in situ &one tiny focus suggestive of micro invasion.Is it cancer?

Yes: Adenocarcinoma in situ is cancer. The area suggestive of micro invasion suggests you should have rather aggressive followup screening which I am sure your doctor has, or will soon suggest. Stay on top of this and follow his/her advice. ...Read more

If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?

Power to invade: Tumors are in fact caused by the accumulation of a series of genetic mutations. If something is going to be cancer, the mutations destabilize the genome and eventually mutations give the ability of the cells to invade and spread as they do early after conception. The idea that tumors are "cells dividing too rapidly" is fundamentally wrong and confusing -- it's the loss of controls. ...Read more

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
