1. Judy has fair skin / red hair‚ her skin has less melanin than Mariah’s. This puts her at higher risk for melanoma than Mariah. 2. Judy observed that her mole was larger and more jagged than she remembered. It was discolored‚ with a raised purplish-black dot. This occurred because cells called melanocytes produce more pigment. Discolored or multicolored moles are considered atypical. 1. Benign tumors have no potential to spread‚ and will not affect the organ’s function. However removal of

Benign Prostatic Hyperplasia Benign prostatic hyperplasia (BPH)‚ also known as benign prostatic hypertrophy‚ is a histologic diagnosis characterized by proliferation of the cellular elements of the prostate. Cellular accumulation and gland enlargement may result from epithelial and stromal proliferation‚ impaired preprogrammed cell death (apoptosis)‚ or both. BPH involves the stromal and epithelial elements of the prostate arising in the periurethral and transition zones of the gland. The hyperplasia

It is known‚ that there are two types of breast cancer: Ductal Carcinoma- starts in the tubes (ducts) that move milk from the breast to the nipple.1 This is the most common cancer in woman. Lobular Carcinoma- starts in the parts of the breast‚ called lobules‚ which produce milk.2 Depending of the severity of the breast cancer‚ it falls into two grading or categories. Those categories
