Acinic Cell Cancer
I need to know if someone can help me out to find information about a diet to combact cancer cells in humans?
Depends: Diet and exercise may be more important as prevention (eat your veggies) and for recurrence risk rather than actively treating a growing cancer. It may also depend on tumor type, where some cancers are oblivious to dietary interventions.

Varies: You start acquiring the mutations that produce cancer when your life starts. Cells that a pathologist can tell are "precancerous" signal "time for treatment". Cases in which the mildest of dysplasias of the cervix have turned to invasive cancer in less than a year are well known. Others simply disappear, or never progress. Be glad for early detection -- and congratulations on a likely cure. ...Read moreSee 1 more doctor answer
They invade : Cancer cells have mutations in what are called proto oncogenes that allow the cell to divide when there are abnormalities in their DNA that would normally be repaired. These mutations allow the metabolic pathway to be altered to use anaerobic glycolysis, produce invasive enzymes known as metalloproteinases and reach immortality by having the telomerase enzyme activated for immortality ...Read moreSee 1 more doctor answer
No short answer: Changes to dna is a final common pathway. Things we do (smoke, drink alcohol, obesity) can contribute. Environmental exposures ( toxic waste, radiation, excessive sun exposure) are also causes. Inherited gene mutations ( brca in breast, hnpcc in colon, men in endocrine tumors) confer higher than average risk for those families. Best to avoid bad things, and do screening tests at the right age. ...Read moreSee 1 more doctor answer
Genes & environment: Cancer arises from genetic changes in cells that lead to their uncontrolled growth. These changes arise from a complex interplay between our inherited genes and our environmental exposures. Hereditary cancers occur when defective genes are inherited, predisposing cells to become malignant. Environmental damage (smoking, hpv, radiation, diet) to cells also can cause these transformations. ...Read moreSee 1 more doctor answer
The story that: Our bodies may develop genetic changes that if not checked could lead to overt cancer, but the surveillance role of the immune system, when working optimally, can identify and destroy. But i'd not endorse the idea that "every human" has viable cancer cells in their body. ...Read moreSee 1 more doctor answer
Confined cancer,,: Cancer"in situ" is cancer that's confined to an area like the skin or the colon and it hasn't broken through the membrane that's containing it. That means it can be fully removed without any left behind. So if it's treated at this stage, it can be cured. It's wise to do check ups in case there's recurrence but that particular cancer would be cured, so get treated while a cure is possible. ...Read moreSee 1 more doctor answer
Yes: Non-small cell lung cancer (nsclc) and small cell lung cancer (sclc) are two different types of lung cancer. They can occur together at the same time. Not very common, but it happens. Some of the same chemotherapies (and radiation) may be effective against both types of tumors. ...Read moreSee 1 more doctor answer
P53 mutation: In addition to the turning on of oncogenes producing proteins specific for cancer, there is a mutation in the p53 gene that controls cell cycle and prolongs interval to division when a mutation in DNA is recognized. This mutation rather than being repaired during the cell cycle is passed on to the next cell in the form of mutated DNA ...Read more
