Does cancer grow faster in someone who is healthy as opposed to someone who is not as healthy?

Example, person A eats healthy, and exercises.  so he gets more nuetrients and they are transported throughout his body more effeciantly, and therefore, would "feed" the cancer more.  As oppose to some unhealthy, sedentary person, assuming there are no other factors for cancer growth, genetics, ect.

Add on, if someone does find out they have early stages of cancer, what would be the best way to slow down the cancer growth?  what foods should the person avoid or eat more of, and if possible, should the person try to remain active (if possible)?

Different tumors have different mitotic rates. Healthy people are overall less at risk for tumors, in part because they have better metabolic balance (there are few "spare" calories in circulation), and optimally functioning immune systems (glycosylation of surface receptors inhibits all sorts of responses, decreased blood flow of a sedentary life style decreases average tissue patrolling by white cells, etc, etc, etc).

If someone has, for example, low-grade squamous intraepithelial neoplasia, or ductal carcinoma in situ, that is, truly dysregulated cell division with a natural population history of disease known to statistically lead to invasive carcinoma in a subset of cases, the best treatment is generally early excision.

Diet is a good preventative, but once the cells are misbehaving, they need to be removed.
