25 male does oral cancer spread fast?have 3mm lump in lower lip for 2 years,hasn't really grown(maybe 1 or 2mm) if cancer would it spread to nodes yet

Lump in lip: The lump is probably a cyst. However, it is always best to have it examined by your dentist or an oral surgeon. If they think it is suspicious, they will recommend a biopsy. It is Always better to be safe.

Mucocele possibly: This bump inside of your mouth may be a mucocele. It is caused when the duct to a minor salivary gland gets clogged or traumatized and the saliva backs up forming a fluid filled bump. They are most common on the lower lip but can occur elsewhere in the mouth as well. Small ones can resolve on their own. Large ones (as shown here) require surgical removal by and oral surgeon.

Cancer, Not Likely: Lip cancer can relatively grow quickly. The risk of developing oral cancer increases over the age of 40. What you are describing is a common benign oral fibroma and they pose no harm. If concerned, see your dentist for investigation.
