No, you shouldn't worry because a tumor can't be spread like a sickness. (Sorry about the hamster)
If the male is with the female when she is in heat, they will mate. It's pretty much a given. They should be separated, inbreeding leads to weak litters.
If the 1 year old hamster is a syrian hamster DO NOT put another hamster with it. They are hamsters that NEED to be alone. If it is a dwarf, hamster, it might be ok. Dwarf hamsters like having each others company. However, if the 1 year old hamster is not use to other hamsters, it might not go over to well.
Hamsters do not socialise with other hamsters, unlike other domestic pr, specificets. Hamsters fight other hamsters in the wild when one gets in to the others' territory. They will bite eachother, specifically on butts!
it will chew on it and eventually it will destroy it If you're talking about a real hamster and not a robotic one; hamsters are pretty unsophisticated when it comes to what they eat. We had a litter once that had one little one that had a bad foot, and the other hamsters ate it - I mean, ALL GONE! It was a little gross, but what do you do? Sorry, but you can't put a Syrian hamster with a Roboroski hamster, because although Roboroski hamsters are social, Syrians are not and will amost definitely fight.
Hamsters are not as smart as a dog or a dolphin. But they are able to understand that some humans feed them and other humans do not.

it depends on the type of hamster you get. you should give baby hamsters away when they are two or three weeks depending n your type of hamster if it is a syran hamster you should give the babys away at two weeks other hamsters you can give it another week
He'll have a little fluffy erection and he should be inserting it into the other hamster, assuming that the other hamster is a female.
Dwarf hamsters - each other and on suitable hamster bedding. Syrian - on their own and on suitable hamster bedding.
well it should say(should i get three hamsters). Yes it is ok if you get three hamsters they like other hamsters.well you should know their are two kinds that dont like other hamsters it is the tedy bear hamster and the golden hamster. if you get two males you should put them together at a young age same with females. but you should only put male and female together if you a ready for baby hamsters.well their you have it! good luck!:-)
Chinese hamsters have tails and dwarf hamsters don't and Chinese hamsters can live together.
There are dwarf hamsters their are Chinese dwarf hamster ( this hamster isn't classified as a dwarf they are just small hamsters) The winter white hamster Campbell dwarf hamster Roborovski dwarf hamster And they are different names and they all have different colors but syrian hamsters have more colors than dwarf hamsters
Not really, most hamsters are very aggressive to other hamsters.
Rolling her and biting her are signs of domination. You need to keep an eye on it. Some hamsters are very territorial, and will fight other hamsters, even if they are female. He can potentially hurt her.
You should never keep two male hamsters together because it might result in fights and one eating the other.
It is proabably a sore. Does it live with other hamsters? If not, you should definentally get it checked.
Unless it was a cannibal hamster, no.
