Hi Lynn, yes, I had the discoloration and lifting with all ten fingernails. I was told to really baby them- wear gloves when doing any type of work around the house, and no prying (think can tabs, etc). I eventually put bandaids on all my fingers with the gauze side against the nail, just in case I might catch them on anything at work- I really did not want to lose any of them. I was able to keep all ten. but then it started with the toenails, too! I had 2 on each foot go dark, and lift. I ended up losing the nail on both big toes! And they grew in all pitted, and discolored- and I lost the one on my right foot a second time!! I wish they had grown in within 18 months! I am now 6 years out of treatment, and I can still tell they are traumatized by the experience! The color is still off, though new growth continues to get lighter in color- and closer to the pre-bc shade! My oncologist never mentioned using the chemo mittens and booties to minimize neuropathy (nerve damage) and it seems that those that do use them, seem to have less problems with the nails.

Keeping you in prayers as you navigate this challenge! Hugs!

Nail changes are a common side effect of breast cancer treatment, including chemotherapy, radiation, hormone-based therapies, and targeted therapies. It can feel alarming, but knowing what to expect can help.

Here are some changes you might notice:

- Discoloration (purplish or darkened tones)
- Ridges or lines across the nail
- Thinning or brittleness
- Dryness or pain in the nail bed
- Nails lifting, tearing, or splitting
- Discharge from under the nail
- Complete nail loss

One MyBCTeam member shared, "Can anyone comment on nail discoloration or loss of nails during chemo? I noticed my two thumbnails are developing a purplish half-moon shape at the nail bed near the cuticle." The good news is these changes are temporary. Fingernails typically regrow within about 6 months after treatment, while toenails can take up to 18 months.

Here are some tips to manage nail changes:

- Moisturize regularly before and during treatment
- Keep nails short to prevent catching or breaking
- Avoid artificial nails during treatment
- Wear comfortable shoes to protect toenails
- Check with your healthcare team before applying nail polish

Always alert your healthcare team to any signs of infection, unusual pain, or discharge under the nails right away.
