Hyperplasia & metaplasia & chronic inflammatory cell infiltration into the stroma = carcinoma?

No: The description you provided is not consistent with a diagnosis of carcinoma. It is more consistent with changes due to chronic inflammation. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.

Not yet: Hyperplasia is a lot of benign cells that are not yet malignant. Metaplasia is transformation of one benign cell type into another benign cell type. "dysplasia" or "atypical hyperplasia" would be a warning of premalignancy. The chronic inflammatory cells are not cancer. This is a benign biopsy -- either no cancer or it was not at the biopsy site. Please follow up as appropriate.
