Lump Growing In Your Foot? A Central Indiana Foot Doctor Explains What It May Be and What You Can Do.

Comments (31)

The sudden appearance of a mass or lump in the body can be fear inducing, no matter where it appears.  Concerns for cancer or an unusual injury run rampant, and the appearance of a new lump in the foot is no different.  While the new mass is certainly not a sign that is normal, most people can rest assured that cancer is unlikely, and fairly uncommon.

A lump or mass under the skin is a sign that tissue of some form has expanded beyond its typical size.  Some causes of  a mass may be fast growing, and some may be slow growing that is simply not noticed until the area is either visible externally or is painful and prompts a personal exam.  In the foot, the most common cause of a quickly appearing mass is a ganglion cyst.  This generally benign fluid-filled mass is what most people have when they see a new lump in their foot or ankle.  An in-depth explanation of ganglion cysts and ganglion cyst explanation and treatment can be found by following the highlighted link.  Cancer within a cyst like this is possible, but incredibly rare.  Other common masses in the foot and ankle that can seem like they suddenly appear include fat tissue masses, masses of fibrous tissue called fibromas, tendon thickening from underlying bone spurs (especially behind the heel)  as well as simple cases of soft tissue swelling/fluid retention (such as often seen in front of the outer ankle).  These masses are rarely ever cancerous, and while they can cause pain do not require urgent surgical intervention.

 

On the other hand, serious cancer can form in the foot, and less commonly may be a metastatic mass from a cancer elsewhere in the body.  These cancers can include rare tumors of skeletal muscle, bone, fat tissue, nerve tissue, blood vessels, and cells that form the tissue in and around tendon.  Some of these rare cancers are potentially fatal, and others create serious but not lethal problems for the health of the foot or ankle.  Treatment for these cancers may need to involve the entire body, and surgery or amputation may be needed in the most serious of cases.  Once again, though, these cancers are RARE.

 

If you notice a mass develop in your foot, the most sensible decision is to start with a foot and ankle specialist who deals with foot anatomy on a daily basis.  A thorough exam by a podiatrist can lead to an accurate early diagnosis of the condition.  If the mass is suspicious, proper testing can be arraigned, as well as coordination of appropriate treatment.  However, over 99% of the time this is not necessary, and the benign lump can be easily treated in the office.

I have lump on top of both feet and a lump on inside of both feet. Also a lump on my eyebrow area which I noticed first. Is it more likely to be cancer with so many? I have an appointment with my primary on Thurs. To get a padietry appointment. I'm scared with so many lumps popping up. What do you think?

Hello,i have a hard lump on the front side of my right foot. I have it well over a year now. I was sent to see a specialist as i suffer from planter fasciitis in both feet as well. He thought it was a cyst and was going to drain it but wanted to do an ultra scan on it as it had very hard from the last time he seen me. They couldn't get enough detail from the ultra scan to see what exactly what was going on,so they sent me for an mri scan. I got a phone call from the doctor saying my results of the mri were sent to a surgeon to look at in more detail. What do you think the likely hood it would be&is it to determine if i need surgery or not. I know your not a mind reader,lol but just wondering what do you think it would be? Thank-you for your help&advice :-)

I have had extensive foot surgery on my left foot five years ago. I still am unable to walk normally and have constant pain. Now I have a lump growing on the side of my left foot. I refuse to go back to the surgeon. What type of doctor should I see about this. The pain is unbearable when I walk.

About 3 quarters of the way down the right side of my right foot (going from my little toe towards my heel) I noticed a pain a few weeks ago. I ignored it thinking it would go away. But it hasnt, it's only gotten worse. Now its worsening week by week. I feel a lump when I run my hand over it, that the other foot doesn't have & I don't think its bone. I think it may be getting bigger as time passes. I changed shoes but that's not it. It has nothing to do w/ my shoes or how much I stand during the day because all of that is normal like anyone else. I'm a bit freaked out really to the point I'm going to go to the doctor tomorrow I think. I keep hoping it will diasappear but it's not & it's getting slightly more painful by the day. Like I said, right on the side (just above the ground) on the right side of the right foot a little more than halfway down. Any thoughts on wtf this could be ??? Of course it scares the 💩 out of me....

Good Day sir, suddenly, a hard lump appeared on both of my feet. One is in the left of my left foot and one is in the right of my right foot. They are round about half an inch in diameter and slightly darker in color than my skin. It is also hard like it's a skeletal formation. This just appeared suddenly after 3 weeks of jogging. It's strange that both of them are proportional in place of their appearance. They are not painful at all though. My concern is, should I worry about them? Will they disappear naturally over time? And what are the symptoms of a cancerous lump? Thank you so much! Good day!

I had a lump appear on the top of my left foot I noticed it when I went to scratch an itch. It had pain that shot up my leg, but I pressed on it to see if it was a solid mass. It disappeared but reappeared above my left ankle bone hrs. later. I have not pressed on it for fear of where it may go next.

I slid into home last night. Right away I noticed some pain in my ankle. I have a small swollen area with a small lump in the sore area. Probably just swelling that caused the lump??

I have a hard lump on the outer side of my foot about midway toe to heel. It feels like a swollen part of the bone of my foot? What could it be?
Posted by Rick on March 18, 2017 at 01:24 PM
If you’re not satisfied,or want more information with what your GP says, you can always make an appointment with any of our doctors, Podiatrist only study from the ankle down, that is there “expertise”, and there is no way for us to make a diagnosis without seeing the lump. Thanks

On my left foot it feels kinda like a bone was sticking out of my foot, but now I am scared it is a tumor (Ps will be going to gp)
Posted by Nufink on March 12, 2017 at 10:42 AM
If it is compressible it is possible that the lump could be a cyst. That being said, many soft tissue tumors and nodules with benign and not so benign origins can feel compressible, and can move into deeper tissue when pressed on if not firmly attached to a strong structure. Having a foot specialist examine the mass is the best place to start- while it could be something simple to treat like a cyst, when dealing with masses one should be cautious and have a formal assessment.
Posted by Dr. Kilberg on March 7, 2017 at 09:19 AM
You spelled arranged wrong, lol. Anyway, my question is, I had a lump appear on the bottom of my foot on the ball of my foot just left of the center, just above where the arch transitions to the ball could that be a cyst as well? It only hurts when I walk on it. If I push on it from the left side of it, it feels like fluid and it will disappear while I'm pushing on it so it feels like fluid
