Getting obsessed with huge quarter size welts-like a blackhead ready to bust! idk what to call them. Is this common...

I appreciate you reaching out, but I want to be straightforward with you: what you're describing sounds like a skin concern that needs evaluation by a dermatologist or your primary care doctor—not something I can assess through a description.

Here's why this matters:

What you're describing could be many things:

• Skin infections or inflammation (very common, not cancer-related)
• Folliculitis or clogged pores
• Cysts or other benign skin growths
• Allergic reactions
• Side effects from medications or treatments
• Other dermatological conditions

The important distinction: While some cancers can affect the skin, the appearance you're describing—quarter-sized welts like blackheads—doesn't match typical cancer skin presentations. Cancer-related skin changes usually look different (unusual moles, persistent sores, discolored patches, etc.).

What you should do:

1. See a dermatologist or your primary care doctor soon - they can examine these in person, which is the only way to know what's happening
2. Take photos if they change or spread - this helps your doctor
3. Note when they started and if anything triggers them (new products, detergent, foods, etc.)
4. If you're in active cancer treatment, mention this to your oncology team too - they should know about any new skin changes

Don't assume it's cancer-related, but also don't ignore it. Skin issues are common and usually very treatable once properly identified.
