I am 19 years old female. I have some doubt about cancer symptoms that I face. First is that my breasts are different size. Right is larger than left. Some times the nipple retracted. And many hairs are surround the nipple. If it seen in women? and I feel some block in throat. After eating food I feel very disturbance. I test the thyroid test. It is normal. I am disturbed by these problems. If tese are the symptoms of cancer?
