Mammogram (Definition)

A mammogram is the "gold standard" screening test for breast cancer. It's well established that yearly 'grams will DX cancers well before they are palpable, leading to earlier diagnoses and saved lives. All experts agree to begin yearly mammograms by age 50; many (including myself) believe the pro's outweigh the con's to begin at 40. Regrettably, less than half of all women ...Read more

Should i start with a screening mammogram for a lump under my arm in rib area?

Should i start with a screening mammogram for a lump under my arm in rib area?

No - diagnostic: Wolf: whenever you are having a problem that could be related to the breasts you should ask for a "diagnostic" mammogram, not a screening. This means any extra imaging that might be needed can be done at the same visit and the radiologist will often talk with you about your results before you go. The sonogram is almost always done when you are feeling a lump as well as the mammogram.

A pimple on my breast has left a small hard lump under the skin. I had mammogram and ultrasound last month which was clear, should I be worried?

Pimples and Boils: Hi!, pimples and boils are caused by blocked and infected hair follicles. They are essentially small abscesses. When the body can't fight an infection it builds a wall around it called a granuloma. It will go away with time, heat may help. If it doesn't go away, make sure to have it re-examined by your doctor. Good luck!

I had blunt force trauma to my upper arm, after two weeks i still have a large painful lump under the skin after two weeks. Not visible. What is it?

I had blunt force trauma to my upper arm, after two weeks i still have a large painful lump under the skin after two weeks. Not visible. What is it?

Most likely blood: You most likely have a hematoma under the skin, this is a jello like collection of clotted blood which accumulates under the skin after trauma. It is usually just treated with pain meds and a heating pad. There could be other causes, but this is most likely, should resolve after 2 or 3 months, if not, see a doctor.

I got the hpv vaccine 2 weeks ago and my arm is still super sore and it has a very hard big lump under my skin.. Should i be worried?

Hard lump: Hard lump at injection site is a small collection of blood called a hematoma. This occurs when the tip of the needle grazes a small blood vessel called a capillary. It isn't dangerous and will resolve on its own.

How come I have a large breast lump but mammogram and ultrasound show nothing?

How come I have a large breast lump but mammogram and ultrasound show nothing?

Lump: Mammography and ultrasound are not 100% sensitive. However, if you have a large palpable lump it would be unlikely that both tests would be normal if it was a large cancer. It is probably normal tissue, but a clinically palpable mass shouldn't be ignored if it feels suspicious. MRI may help in this situation, or you may need biopsy. Talk to your doc about next steps.

Hematoma?: Sometimes a mammo can cause some local trauma and give you a hematoma (collection of blood) . Best to have it examined to be sure.

May be: A breast cyst. See your doctor for a repeat examination. A new ultrasound may confirm a cyst, or simple needle aspiration may also resolve it.

Left breast lump found on BSE; had mammogram followed by U/S. Complex cyst w/debri (5mm) identified. Told to have repeat mammogram in 1 year but how do I know for sure the "debri" isn't worrisome? Should I get 2nd opinion or request biopsy?

Breast cyst.: Given that your age does put you at risk for breast cancer, unfortunately, with or without a family history of such, a second opinion wouldn't hurt. Complex cysts are a bit more worrisome than simple cysts as they have some contents. I wouldn't panic right now, but a second opinion or a breast MRI wouldn't be a bad idea.

Breast abscess?: If you are breastfeeding, it maybe a breast abscess. Symptoms include painful local swelling + breast lump, redness & tenderness of the breast. In non-lactating women subareolar breast abscess may develop representing an infected lump just under the areola. Inflammatory breast cancer is much less likely, but you should definitely get an ultrasound and possibly a mammogram (if not breastfeeding).

I'm getting lumps on both my armpits, underneath the skin and two of them are painful to touch. Should I be worried?

I'm getting lumps on both my armpits, underneath the skin and two of them are painful to touch. Should I be worried?

Pain in armpits.: There are generally two things of concern that could occur in the armpits. You could be feeling inflamed lymph nodes, wherein the question would be as to the reason they're inflamed. Or this could represent a rather stubborn infection called hydradenitis suppurativa. Regardless, you should be evaluated for this locally, as treatment may be needed.

Have them checked: Tender axillary nodes can be a sign of infection such as a virus but if they are only on one side, you need to see a doctor to rule a more serious cause, .

Hello I woke up this morning and was stretching I reached towards my right armpit and felt a little painless lump underneath my skin. ?

Lymph nodes?: This is most likely a normal lymph node. If it becomes tender or it is increasing in size I would see your doctor. If it moves around easily under the skin it probably a lymph node. If it seems to be stuck down and immobile this would be more concerning for a malignant process.

Painless lump under the skin of my armpit. I can feel it on the surface of the skin. It bleeds when I poked a hole.Looks like regular skin but darker?

Lump in armpit: If you shave or wax there, it may be an ingrown hair that has caused a small collection of oil/skin that you can feel, like a pimple. It is common in that location. Try soaking it for 20 minutes or so, a couple times a day, to see if it comes to a head so you can get it to open up and drain. If it is red, tender, a doctor can open it for you.
