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

Can thyroid adenoma develop into carcinoma?

Can thyroid adenoma develop into carcinoma?

No: A true thyroid adenoma is a benign tumor. However, this can only be accurately assessed once it has been removed surgically -- not by fine needle aspiration. There are molecular alterations seen in carcinoma than are not seen in adenoma. However, some of the molecular changes are cumulative, like p53 mutations -- which are expressed in higher frequency in cancer. ...Read more

Is the risk of thyroid carcinoma increased with diagnosis of hashimoto thyroiditis when multiple thyroid adenomas are present. Tyab 2470?

Is the risk of thyroid carcinoma increased with diagnosis of hashimoto thyroiditis when multiple thyroid adenomas are present. Tyab 2470?

Not if they function: If the adenomas are "cold" or do not function, then they are likely to be malignant. They do not show up on radionuclide scan because they do not function. Otherwise they are unlikely to be malignant. However, since you have many of them, you likely need and should get further workup, like aspiration biopsy, etc., along with treatment for your hashimoto's. ...Read more

Is hurthle adenoma a type of cancer?

Benign : Technically, it can be benign or malignant, so it has to be surgically removed and histologically examined for malignant criteria. If the pathology report comes back as hurthle cell adenoma, it's being considered as benign because there weren't any features that suggested a malignant hurthle cell carcinoma. ...Read more

My tg level after thyrodomicty because of hurtle adenoma is less than.2 and TSH is.04 but have tgab is it mean cancer?Which is good tg and TSH or tgab

Quit worrying about: Your thyroid cancer specialist will guide you further.
I would ask you not to worry about these blood tests as they are not particularly reliable. As long as your cancer has been removed and it was early, you have little chance of recurrence of your cancer. Most times we have to rely on a visible tumor growth before we can take it as evidence of recurrence, blood tests are not all that helpful. ...Read more

tubular adenomas: The fact that you have tubular adenomas at such an early age probably does slightly raise your lifetime risk of colon carcinoma. However, now that you know you can have careful followup and screening to make sure all adenomas are removed before they can develop into colon cancer. ...Read more

Could my son get cancer if he was diagnosed with pleomorphic adenoma, 3 tumors in the neck and 1 in cheek?

Rarely: Pleiomorphic adenomas are benign tumors of saliva glands. It is unusual for them to be in the neck itself, but they can arise "rests" of salivary tissue in the neck. They tend not to spread to other parts of the body but can grow back in the areas where they arose in about 20% of patients who had surgery. Rarely they can turn cancerous and spread to other organs. Best wishes. ...Read more
