The section discussing premalignant tumours says that "tumors may be benign but at risk for degeneration into malignancy". This contradicts the definition of benign given earlier.
Since "benign" was defined as "...which, untreated or with symptomatic therapy, will not become life-threatening", a premalignant tumour is not one which can be left untreated, therefore no premalignant tumour can ever be "benign", unless the definition of benign is amended in some way to talk about immediacy.
It may be that article correctly describes the actual current usage of these terms, which may possibly be rather imprecise. I don't know. User:CecilWard
I agree with you. There is quite a contradiction here. I think the sentence which includes "untreated or with symptomatic therapy, will not become life-threatening" needs to be reworded. There is an emphasis made in the article that the terms "malignant" and "benign" refer to the behaviour of the tumour. It would seem to me that scientists have yet to be able to differentiate between tissue which is benign, and tissue which acts benign but has the ability to become malignant. For that reason, a another definition for potentionally-malignant benign tissue needs to be made. These are just my thoughts, I would like to ask an oncologist about this.

Tumours are able to be classified as benign/malignant based on their histological characteristics - cellular pleomorphism, nuclear pleomorphism, hyperchromic nuclei, increased nucleus:cytoplasm ratio, increased mitosis and the presence of tumour giant cells tend to be seen in malignant cell masses. Metastasis is a defining feature of malignancy, though invasion is very common. To call a cancer benign simply means it lacks malignant characteristics; not that it is not dangerous. Gliomas are a good example (benign brain cancers - compress the brain against the skull). Correspondingly, some malignancies aren't too dangerous, at least relative to some of the nastier benign lesions.

This is a process known as malignant degeneration in which a previously benign lesion by process of de novo mutation has gained the ability to invade and/or metastasize. [1] TaylorM05 ( talk) 17:19, 8 June 2014 (UTC)

I propose we move the content of this page to
benign tumor (currently a redirect) and make this a disambiguation page. Lots of things can be described as "benign" that have nothing to do with the content on this page, and by formalizing the de facto subject of this page (benign tumors) in the title, it will be possible to structure it better. Right now, the page is confusingly written, as the authors struggled over two meanings of the word "benign". An alternative would be to use the even more specific title
benign neoplasm, but that might be too technical for wikipedia, and a discussion of benign tumors that are not neoplasms would be an interesting addition. -

I had a rather large mole removed that was on my chest, the color of it was not concerning to the Doctor, but the size was for me so I had it removed. The biopsy word they used in the letter they sent me was { the results have come back are Benign? ok so my question is was does that mean the word { Benign}?

I removed the sentence "The term "benign" implies a mild and nonprogressive disease." because, in regards to benign tumours, it does not mean nonprogessive disease. In fact many benign tumours will progress to malignancy. — Preceding unsigned comment added by Simoncaulton ( talk • contribs) 21:19, 24 March 2013 (UTC)
I have also removed the sentence " Some types, such as teratoma, are notorious for cancer progression." because I couldnt find any references pointing out that teratomas were particularly prone to malignant progression.
Feel free to put it back in with a reference. Simon Caulton ( talk) 15:44, 31 March 2013 (UTC)
The image used in this article is a strange choice - it is labeled as "Normal Epidermis and Dermis with Intradermal Nevus 10x-cropped," but the benign process in that original image (available here), the intradermal nevus, has been cropped out. As such, the portion shown is just normal skin. The caption could be changed to "Normal epidermis and dermis," but that doesn't help the fact that this article is supposed to focus on benign tumours.

The Mechanism section does not contain any description of an actual mechanism to cause a tumor to be malignant vs benign. It simply states that benign tumors do not spread. If someone could add a section about the actual mechanism, it would fulfill the purpose of the section better. 2605:A601:A918:9600:CB2:8B50:A130:4C9B ( talk) 16:42, 8 March 2023 (UTC)
