Just being safe: Dense breasts in younger women can be hard to read with mammos so your doc wants to evaluate them with another modality. Don't get nervous, just get the ultrasound and make sure your doc keeps you updated of what it shows. Best to you.

Not sure...: I'm a breast radiologist. Something doesn't make sense. In the absence of symptoms (with negative mammo and physical exam), there is no indication for a diagnostic ultrasound. What occasionally happens is something worded in the mammogram report makes the referring physician uncomfortable and additional testing is unnecessarily ordered. I would call to clarify, but i wouldn't worry if i were you.

Adjunct screening ultrasound in dense breasts is gaining traction in states with legislation requiring that patients are notified that they have dense breasts, and that dense breasts decrease the sensitivity of mammography. New York is one of those states. I practice in NY, and since the law went into effect we are doing a ton of them.

Dense breasts: are normal, but dense breasts are an independent risk factor for breast cancer, and can decrease the sensitivity of mammography for detecting cancer to lower than 50%.There are studies showing that the addition of adjunct screening ultrasound to mammography in dense breasts can almost double the sensitivity for cancer detection, and there are many around the country who are doing it,like your doc.

A 18-year-old female asked:

I had a blister on my toe but the skin broke and now there is just a piece of skin hanging there and it hurts. What do I do? When will it heal?

The loose skin : Should be trimmed away, the blister cleaned, then dressed with an antibiotic ointment and then covered with a band aid. It will take a few days, but the soreness will gradually decrease as the skin under the blister dries out and toughens up.

Doctor can evaluate: For new onset of asthma symptoms in an adult, he can see and follow-up with his primary care doctor. If symptoms are difficult to get rid of, or are unusual, the patient can see an allergy & asthma specialist, and/or see a pulmonologist (lung doctor). Pulmonary function tests and allergy tests can be helpful when looking for the best treatments. For bad symptoms, the E.R. Is the place to go to.

A 44-year-old female asked:

Is there any maintenance medicine aside from herceptin (trastuzumab) for her2 positive breast ca patient?

Possibly: In the adjuvant setting a hormone blocking agent such as an ai might be used. That would be for hormone sensitve tumors. In metastatic disease the situation can be more complicated. In that case Herceptin could be used as a maintaince agent. Other drugs such as tykerb, (lapatinib) perjetta might fill this role. If you could give more details, i can be more specific.

Unlikely: If all testing negative, i doubt it. You may have simply not ovulated last cycle and that is why you are so late. Are your periods normally regular? Check with your obgyn and good luck.
