it isn't spread, it develops from other causes
It is also spread by germs. But orignally this disease can be spread by the cells throughtout the body.
some are flu , HIV , std
leukemia is a cancer of the white blood cells in humans, not plants therefore your answer is animals.
Malaria is transmitted among humans by female mosquitoes of the genus Anopheles.
It is not spread among humans, but it is spread throughout the body by the cells. Leukemia is cancer of the white blood cells. Like other cancers it is not contagious. White blood cells help to fight infections, so obviously a person with Leukemia is unable to fight off infection. However, if caught in time it is one of the more curable cancers.
Leukemia
Humans began in Africa and spread from there.
It deals with one's family history, personal health, eating habits, etc. It's not contagious.
Absolutely not. Leukemia is a form of blood or bone marrow cancer and is not transmitted through needles, sex or any other methods, unlike AIDS and HIV. I know because my loving husband has lived with it bravely for years.
No, distemper cannot spread to humans. It is a disease that primarily affects animals, especially dogs.
No, cats cannot spread lice to humans. Lice are specific to humans and cannot survive on animals like cats.
Edit - leukemia in cats is NOT the same as leukemia in humans. It is NOT cancer NOR is it a death sentence. I had a FeLV (feline leukemia virus) cat and a FiV cat (feline AIDS) and both cats lived to be 20 and 22, respectively. Yes, he really does. Leukemia in cats is not an automatic death sentence, he has probably got a 50% chance of surviving at least three years. A few cats are carriers who never get sick at all. It's a fairly common, easily-spread disease in cats. There are treatments but no cure, but there is an effective vaccine. Good luck Sparta, we love you.
