Have you diagnosed someone young with intraductal papilloma, carcinoma in situ or breast cancer?

Yes. While these diagnoses are less common in young women, they do occur. If you have concerns, you should consider getting an ultrasound or a mammogram.
Actually I see them. Young and old after the diagnosis of papillary adenocarcinoma confined to duct, ductal carcinoma in situ and invasive cancer. The first 2 are quite benign, but portend of the potential to develop invasive cancer. Invasive cancer can arise in the duct or in the lobules. The special bad feature of younger and especially african american women is "triple (receptor) negative" - no er, pr or her-2-neu.

What causes breast bloody discharge beside cancer or intraductal papilloma?

Fibroadenoma. And bloody discharge is more likley to be benign than invasive cancer...Problem is benignancy and malignncy cannot be discerned until it is removed and margins and receptors assessed.

Is ductal carcinoma in situ really breast cancer? Can lifestyle, nutrition or supplements affect its course or occurrence?

DCIS. We dont consider dcis as an invasive breast cancer- rather we consider this as a precancer condition./ a non-invasive breast cancer- localized only on the duct or stage t0. You are right -there are a lot of factors that perhaps can contribute to development of cancer- like lifestyle/habits (smoking/alcohol, lack of exercise), nutrition/diet (certain food/amino acids that is carcinogenic) etc.
YES. Ductal carcinoma in situ means that the cancer is there in the duct but it has not invaded into the surrounding tissues of the breast. This means it was found early. Can living a healthy lifestyle help? Yes it can but it cannot fix it. Get this removed before it becomes a more progressive invasive cancer.
Yes and No. Ductal carcinoma in situ is basically a cancer which has not yet become invasive. The only way to treat this is to get rid of it before it turns into an invasive cancer. Because it is detected early, surgery provides a high rate of cure.
Precancerous. Carcinoma in-situ is just one step short of cancer. There is no scientific evidence for or against life style changes altering the course of in-situ lesions. You may engage in life style changes that promote a healthy life style but should not omit conventional treatment. Steve jobs low grade cancer became fatal while he tried to treat it by alternative methods. See your doctor.
Another point. In addition to all of the other answers, there are some new ideas about this problem. The danger with this disease is that you are more likely to get invasive cancers. There is a recently developed test that can give a much better idea of who will get invasive cancer, and who benefits from radiation.

What can I expect if I've been diagnosed/treated for breast carcinoma in situ?

Excellent. Very good news. In situ or non-invasive breast cancer is stage 0. Follow your oncologist's treatment recommendations, have yearly physical examination & mammograms. Should have an excellent long term outcome but keep a watch out for new breast lesions.
Should be fine. You will need to have a surgery to remove the breast carcinoma in situ. In addition to that -if you have a lumpectomy- you would need to get an a radiation therapy following the surgery to reduce risk for recurrence and tamoxifen would be recommended to take for 5 years. You should have a mammogram yearly basis and self breast examination is recommended. Prognosis is good as it is not invasive.

After a papilloma biopsy was the chance of getting breast cancer?

Slightly increased. Intraductal papillomas are benign breast duct tumors that are often associated with nipple discharge. Women with papillomas have a 1.5-2 fold increased risk of cancer. When a papilloma is found in the periphery of the breast (away from the nipple), it should be surgically removed to be certain that there is not an underlying cancer present.
Same. You risk would be the same as before the biopsy.
Needle biopsy? If this was a needle biopsy, it is recommended that the papilloma be removed because of a small chance that there is cancer at the site. This risk is higher if there was atypia in the biopsy. If this was an excisional biopsy (a surgeon removed it) then there is only a small increased risk of breast cancer in the future.
