Strange pale spot on Abdomen

[Vlad805]

Hello I'm new to the group. I actually joined because I'm slightly worried about my new Mexican Red Knee. I have had her since last October and she has molted once in my care roughly a month or so ago. Just yesterday I noticed a strange looking spot appear on her abdomen. When I first got her she had a prominent bald spot (probably due to kicking from stress as well as getting ready to molt) and this spot doesn't really match the coloration of that said bald spot. I was hoping you guys can take a look at it and let me know if it's something you have seen in the past. I was told by someone that it looks like it could be a cancer... I really hope not because I just lost my beloved Rose Hair after 10+ years of owning her and I was heartbroken.

Below is her husbandry

Substrate: coconut husk
Hides: tree bark (not sure what kind)
Food source: store-bought crickets
Hydration: filtered water
Temperature range: 70-80 degrees (70 on cold side and 80 on warm side)
Humidity: 50ish

No pesticides used in the house at all.

Also another sidenote is that she has been very active lately! At first she spent most of her time in her den, but recently has been moving around all over the enclosure and when climbing up the glass. She's been eating, but recently started refusing meals.

That is what I was hoping to hear. The coloration is what threw me off...

Their skin is normally that colour but it darkens just before a moult

That is the peculiar part... You can't see it in the picture, but she has a balding spot rightnext to the pale spot and her bald spot is a dark brown.

Not to worry. Multicolored spots, even on the carapace, can be normal molt variants. As far as I know, a tarantula has never been documented to have cancer.

So since I last posted that spot has been getting smaller she at this point it's very hard to see so I think it was either get balding or maybe she got some poop on herself and it's been rubbing off more she more.

Like everyone else has said, no worries. Also, I don't think that the bald spot has gone any smaller. You just don't see / pay attention on it as much as at the first time because the loose hair has dropped off

Here's the butt of my genic right after she kicked some hair at me. Small, loose urticating hairs are very light in colour.
