A lumpy, bulky armpit is often not fat alone but axillary breast tissue: breast gland left over from the “milk line” we all have before birth. It tends to grow at puberty, in pregnancy and breastfeeding, and with hormonal changes such as major weight gain, when it can become painful before every period. After puberty or breastfeeding it may settle on its own; painful or growing tissue usually needs treatment. An armpit lump neither proves nor rules out cancer, so assessment starts with a surgeon’s examination and a sonomammogram. Axillary breast surgery is done under general anaesthesia, with about 5 to 6 days off work.
You’re relaxing on the sofa, stretched out, arms behind your head after a long day at work. Suddenly, someone pokes you gently in the armpit- your spouse, your child or even your mother. Delightful squealing and playtime begins with the tickle-fest. Sounds like fun, doesn’t it?
Sadly, there’s a subset of the population which can never fully enjoy this scenario. For them, armpits are bulky, lumpy, painful things that must be hidden from sight and touch at all times. Yes, I’m referring here to those afflicted with Axillary Breast Hypertrophy (Enlargement). ABH is a medical condition where the armpits have excess fat and breast gland tissue. So what does this mean? Let’s simplify it.
Why Breast Tissue Grows in the Armpit: The Milk Line
Biology first- we are mammals i.e. milk gland bearing species. Both males and females in homo sapiens carry milk ducts in the front of the chest. But if we rewind to when we are in our mother’s womb, the milk ducts appear within what is called the milkline- a line that runs from armpit above to the private parts below. Most of this milkline recedes before we are born and we are left with a pair of nipples in the front part of the chest with its milk producing apparatus. Sometimes though, the beginning of this milkline in the armpit never really fades. It sits quietly, biding its time, doing nothing. Then BAM- a fully grown lump is seen in the armpit!
The 3 Times Armpit Breast Tissue Grows
When does this occur? 3 main times-
- Puberty- In girls who attain menarche, there’s a previous phase called thelarche- literally, the beginning of breast growth. The armpit breast tissue (when present) gets activated at the same time as the regular breasts and grows at a phenomenal rate.
- Breast-feeding- Pregnant ladies grow bigger breasts during pregnancy in order to be able to feed the little one when it arrives. The axillary breast gets the same memo and grows too. Not that it actually contributes anything to actual milk production but thinks that it will get a participation certificate if it grows large enough. Sigh.
- Hormones not related to pregnancy- Massive weight gain or specific types of stress can trigger excess oestrogen production and this lovely female hormone causes breast size increase similar to puberty. The real downside to this particular cause is that the ABH can be particularly painful. Every menstrual cycle can bring both growth and also intense stabbing pain prior to cycles.
When to Wait and Watch, and When to Treat
Points 1 and 2 can adopt a wait and watch approach as there is a chance that when the hormone levels stabilize, the growth of the ABH will slow and stop. Maybe even reduce in appearance, though this is very unlikely. Point 3 is where most of my patients come in. Painful swelling in the armpits which worsens every month and causes awkward clothing choices. 2 good reasons to get it treated then and there. In addition, if there is a history of breast cancer in the family, women will get mighty concerned about this lumpy mass in the armpits.
Is a Lump in the Armpit Cancer?
To clarify- the presence of a swelling in the armpit does not mean it is cancer, nor does it prove the absence of cancer. The only reliable way to determine whether something is cancer starts with a physical examination by a Surgeon. That is a whole different chapter.
How Is Axillary Breast Enlargement Treated?
So the question remains, how is ABH treated? At Dr. Amrika’s Aesthetics on Sarjapura main road, I start with a detailed medical examination and check the sonomammogram results (this is an ultrasound of the breasts and armpits to determine whether there are any other lumps that clinical examination missed). Having understood all the pros and cons of the procedure, the patient picks a date for this surgery and, under General Anaesthesia, it is performed. If you are curious about the exact details, it’s there in the website’s Signature Surgery page as well as on my socials, so see those.
Why Some People Put Off Surgery
Let’s try to understand why someone may opt out of the surgical option.
- Fear- this can be fear of pain, fear of surgery or fear of making things worse. Yes, surgery can be painful and scary, but that’s when guidance and pain-management strategies can be used effectively. ABH surgery can be virtually painless in most cases.
- Uncertainty- most patients are very unsure about whether ABH will get resolved with surgery in the first place. To this I say- don’t take anyone’s blind opinion on this. Read the literature, look at the data on surgery vs non-surgical methods and make a judgement call. Else delegate this task to someone you trust and let them help you make a good decision.
- Money- that price tag pinches when it is placed in the file. It can certainly swallow up most of a typical paycheck. That is as it should be. Gold prices do not reduce as per our needs, so why assume that prices in Aesthetic Surgery (which I think far outweighs gold in terms of value) will listen to need? Besides, with easy finance options, most people who need this procedure can afford it with no more fuss than buying a cellphone on EMI.
- Time- now this reason is a genuine one. If one doesn’t have the luxury of about 5-6 days of time off work and chores, then postponing the procedure makes sense. If you can arrange for support for these many days, surgical recovery becomes straightforward.
- Age and Present Physical condition- young girls who are just past menarche and not yet fully grown as well as breastfeeding mothers are not good candidates for this procedure. Too many variables and it can get messy.
Is It Vanity to Want Your Armpits Fixed?
The last point here is that even if there is no pain and not much growth, rather the lump is primarily for Aesthetic purposes, then that is also a valid reason for opting for surgery to fix this. It is not vanity when something safe is available to make yourself feel better. And even if it is plain vanity, so what? It’s not like we roam around naked and live in trees to chase the perfect “natural” way of living, so why be hypocritical regarding a procedure that can safely reshape armpits?
Everyone has the right to be tickled in the armpits without fearing judgement of the lumps within them.
Frequently asked questions
What is axillary breast enlargement?
Axillary breast hypertrophy (enlargement) is a condition where the armpits carry excess fat and breast gland tissue. The gland is left over from the “milk line” that runs from the armpit to the groin before birth. Usually the line fades, but the armpit end sometimes stays and grows later in life.
Why does breast tissue in the armpit grow?
It responds to the same hormones as the breasts, so it typically grows at three times: puberty, pregnancy and breastfeeding, and hormonal changes outside pregnancy, such as massive weight gain or certain types of stress that raise oestrogen. In that last group it can be painful, with growth and stabbing pain before periods.
Can axillary breast tissue go away on its own?
After puberty or breastfeeding, a wait and watch approach is reasonable: once hormone levels stabilise, the growth may slow and stop. It is very unlikely to shrink noticeably on its own.
Is a lump in the armpit a sign of cancer?
A swelling in the armpit does not mean it is cancer, nor does it prove that cancer is absent. A reliable answer starts with a physical examination by a surgeon. At Dr. Amrika’s Aesthetics this is followed by a sonomammogram, an ultrasound of the breasts and armpits, to look for any lumps the examination may have missed.
How long is recovery after axillary breast surgery?
Plan for about 5 to 6 days off work and household chores. With support at home for those days, recovery is straightforward.
Who should wait before having axillary breast surgery?
Young girls who have only just started their periods and are not yet fully grown, and mothers who are still breastfeeding, are not good candidates. The tissue is still changing in both groups.
How much does axillary breast removal cost in Bangalore?
At Dr. Amrika’s Aesthetics, indicative pricing is ₹80,000 to ₹98,000 for both sides, all-inclusive. The exact quote is confirmed at your consultation.
