Yes. It is estimated that10-15% of all breast cancer cases in the US are hereditary. A simple blood test exists to see if someone has a genetic mutation responsible for many of these hereditary breast cancers. If someone has this mutation, they have as high as a 65% chance of getting breast ca in their lifetime. Their children have a 50:50 chance of inheriting this mutation.

When do you get regular mammograms? Breast cancer does not run in my family, but I want to make sure I'm doing everything to stay in good health. At what age do you recommend women start getting mammograms?

Currently, . Currently, at our institution we recommend that a woman with no risk factors begin yearly screening mammography at age 40. However, the recommendation for beginning screening mammography has become more controversial due to the recently published recommendations by the us preventative services task force which recommends screening mammography for women age 50 to 74 years. A rationale behind this recommendation is that screening mammography in women age 40 - 49 years results in more false positive results with comparatively few cancers detected. Currently, both the american college of radiology and the american cancer society recommend yearly screening beginning at 40 years of age.
At 40. For my patients, I recommend a yearly mammogram starting at age 40.
40. You should start getting annual mammograms at age 40.

What is coming out of my nipples? Only when I squeeze I get a semi-thick white substance. I can see it under the skin before I squeeze it. Breast cancer does run in my family. I am 19 years old. No babies, no piercings, no birth control.

The. The previous two doctors provided excellent information. If the material came from the area surrounding the nipple and not from the nipples themselves, it could be a lubricant from the montgomery glands. They are in the dark skin surrounding the nipple (areola). These glands may blend in with the skin or may look like small bumps. If that is the case, try not to squeeze them.
You. You describe leaking a white substance, which is probably breast milk and we call it galactorrhea. Breast milk formation is abnormal if it occurs more than 12 months after pregnancy lactation. You should have this checked to understand the cause. Galactorrhea is caused by an excess of a hormone called prolactin. Excess prolactin can be caused by intense suckling, medications, low thyroid hormone conditions (hypothyroid), excess estrogen (birth control pills), stress, some unusual brain lesions or even non-cancerous pituitary tumors. If the galactorrhea is caused by a specific disease then you need the disease treated. If there is no significant disease and the amount of discharge is minimal then sometimes no treatment is necessary. If the galactorrhea is causing embarrassing wetness or simply bothers you but there is no other serious disorder then medication can stop decrease the prolactin levels and the breast milk. Good luck.
I. I agree with dr. Opshahl that this is probably breast milk. The only way to tell for sure, though, is to see a doctor. So you need to do that. In the meantime, do not squeeze the breasts or try to get the milk to come out. That only makes things worse. Wear tight bras like sports bras. This can also cause your periods to become irregular or stop altogether, so be prepared for that too. This is not something that should be ignored, so talk to your doctor soon!
See your doc. Cancer would not be the first thing that I think of. You should alert your friendly primary care physician to these symptoms. Most likely physiologic.

, ovarion or breast cancer dies not run in my family. May I safely continue hormone replacement.

Yes. As a neurologist, I am bias towards HRT because of known risk of dementia. I am sure oncologist would beg to differ with me since they are biased towards their profession. Very little to suggest if any that if there is no familly history, that HRT puts you at risk for cancer.
Be careful. At your age, the risk with hormone therapy increases. You need to be careful. When treating with hormones, you want to use the smallest dose possible and treat for the shortest time possible. It is very important that you meet with your physician to discuss your risks and consider checking genetic studies, and hormone levels. Make sure you are screening for breast disease as well. Be careful!

What happened with breast cancer foundation run for the cure?

Doing well. Despite an overly publicized political fiasco related to funding planned parenthood mammograms, the susan g. Komen foundation is thriving and continues to do wonderful work to provide services to underfunded women and to contribute to breast cancer research.

I'm on estrogen pills how long should I take them before they run a risk of causing breast cancer and should they be took along?

They don't.. Estrogen pills do not ause breast cancer. They can however make a cancer grow if the tumor is sensitive to estrogen. The lenght of time you can take the pills should be decided by you and your doctor.
5 yrs or less. It has been shown that using hormone replacement therapy (hrt) can increase one's risk of breast cancer when taken for longer than 5 years. Because of this we no longer recommend taking hormones for long periods of time. Work with your gynecologist for options to deal with the symptoms of menopause.

Hypothyroidism, take 50mcg Thyronorm daily. Read that HRTs like the above increase risk of breast cancer in long run. Is this true?

Not with this hormon. The word HRT means use of female Hormones (like estrogen/progesterone) for post meopausal symptoms like hot flashes etc. What you are taking has no effect on the breast, only estrogens do.

Any ideas why I would be running fevers after finishing chemo for breast cancer in nov? I ran a fever at night for 10+ days in early dec & again now.

Puzzling. By now your blood counts should be normal (have they been checked?). Also, how high is the fever? Any associated symptom? Any new medication? You need a full physical to try to disclose the source of that fever, may have nothing to do with your cancer or the chemo but it certainly needs an evaluation.

YES YES YES. Especially first degree relatives with breast cancer such as one mother or sisters (or father or brothers for that matter). If one of these family members were diagnosed under age 50, that's also and important fact. Consider genetic counseling.
