I'm not sure if that's what the fish has, but you shouldn't have eight goldfish in a ten gallon tank. Goldfish can live for a very long time and grow to enormous sizes, but you have to take proper care of them. It should be 30 gallons for the first fish and ten gallons for each additional, so 100 gallons in your case. Also, goldfish like to be in schools of three, so adding one more would be ideal.
Are the scales just protruding or are there definite bumps? Either way, you'll need to set up a hospital tank for the fish. Research the symptoms and medications and bring pictures of the fish to a pet store or aquarium where someone could properly diagnose it. Best of luck to you and your fish!
because your goldfish has a tomber(cancer)

Usually no, you should get it treated immediately.
This is probably just a natural color change. This is common in goldfish. If you notice any strange behavior, take it to the vet.
If these "bumps" are whitish they are indicators that the fish is a male and in breeding condition. So in all probability they are good signs rather than bad ones.
This info is from the internet: if you want to get some baby goldfish, the most fascinating way of obtaining them is of course to breed goldfish in your own aquarium or pond. A goldfish becomes sexually mature when it is around one year old, but will not reach their prime until two years later. It can be hard to distinguish a male goldfish from a female goldfish, but when they become mature the female will usually become a little plumper than the male. The male goldfish will develop small bumps on his head, and when the spawning period begins those bumps will be easier to notice since they will become white. Someone says they eat worms, but they don't so don't try it.
If they are little white bumps just on the gills, then you have a male goldfish that is ready to breed. If the white dots cover its body then your fish is sick with ick, and you will need to go to the petstore to get meds. for the fish.
There like "Hey babe, want some fish food" Get it??...You got no sense of humor pal!
