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

Does smoking turn a benign cancer malignant?

It probably can.: There are many times when smoking, often in combination with alcohol, can cause tumors, and make tumors more malignant, like esophageal cancer and lung cancer. Passive, or second-hand smoking, can increase risk of cancers, like lung, breast, and renal. Smoking has been shown to be a promoter of many cancers like lung, anal, and pancreatic. It interferes with apoptosis or death of cancer cells. ...Read more

If a person has a history of benign cancer, are they more likely to develop malignant tumor?

If a person has a history of benign cancer, are they more likely to develop malignant tumor?

Nomenclature: Confusing! "benign cancer" is a contradiction in terms, but there are benign tumors (can grow huge but can't invade or spread), and there are cancers (like basal cell of the skin or many bladder cancers) that are slow and pose little short-term danger. There are genetic disease with multiple benign & malignant tumors; otherwise, tumors occur depending on risk factors and dumb luck. ...Read more

When a biopsy is done by needle, is it possible for the dr. To tell immediately if the cancer is malignant or benign?

When a biopsy is done by needle, is it possible for the dr. To tell immediately if the cancer is malignant or benign?

Not w/o Pathologist: Regardless of the method of biopsy, the only way to DX cancer is to look under the microscope. There are "frozen sections" that can be performed by pathologists within minutes of a biopsy; however, this is not as accurate as staining the tissue (overnight) and compromises our tissue sample. The waiting is the hardest part, no doubt--most often, we can get the results the next day. Hang in there! ...Read more

How do I know if a benign tumor will not turn into malignant cancer in future ?

How do I know if a benign tumor will not turn into malignant cancer in future ?

Unlikely: Not enough info to answer your question. If this is about a lung nodule, it's usually is benign if there are certain characteristics on ct or if it has been stable over 2 years period.

Can I trust skin cancer apps, like skinvision to find out if a mole is benign or malignant?

Can I trust skin cancer apps, like skinvision to find out if a mole is benign or malignant?

Minimally: While skin cancer apps are getting more reliable, they are not yet sophisticated enough to replace an exam by a dermatologist with a dermatoscope and they certainly cannot replace the diagnostic accuracy of a biopsy. While consulting an app may be helpful, seeing a specialist is best to resolve your concerns. ...Read more

Is a seborrheic keratosis is a malignant skin cancer tumor or benign?

Benign: Sk's are easily confused for skin cancers due to their large size, irregular shape, and being multicolored. A trained dermatologist can easily spot the difference but very confusing for patients and other doctors. People can have hundreds or even thousands of sk's on their body and they are all benign. But having these cover the body may make it difficult to monitor for skin cancers. ...Read more

Hi guys. Can anyone tell me what are malignant and non malignant cancers?

Hi guys. Can anyone tell me what are malignant and non malignant cancers?

Malignant vs. benign: In the pure definition, cancer, is generally considered to be "malignant", meaning having the ability to not only grow abnormally, but to invade other tissue types and spread. Sometimes we describe a tumor (a growth of cells) as either "malignant" (a type of cancer) or benign (which is non-malignant or non-cancerous). An example might be a fibroid or leiomyoma of the uterus, usually benign. ...Read more

Malignant (Definition)

The term malignant can be used in several medical contexts, but is primarily used to describe cancers. More dangerous and disorderly than the benign growth of cells, malignant cells have developed genetic changes that can allow it to invade other tissues in an unregulated way. These tumors can later spread, or metastasize, to other parts of the body and ...Read more
