No, tumors are overgrowth of tissue caused by a few different conditions, but none are infectious.
None
no cancers are not contagious at an stage.
Yes, but not because they have it, it is not contagious. There may be genetic factors involved in some cancers, but environmental factors appear to be the biggest determiners.
I know that cancers aren't contagious and what not, but I've recently read up on things that (can??? can it or does it?) cause leukemia. For example, the human t cell leukemia virus. It says that can associate with leukemia, and that virus can be spread through sexual contact. So if that's the cause of it, then wouldn't that imply that I, if involved with that, could get that virus and potentially leukemia or forms of it? Or is there something im like misreading, or misunderstanding. It's all kind of confusing. So i mean, is there like a "natural" form of leukemia that's caused by unfortunate circumstances (like breast cancer) as well as leukemia that's derived from a virus which is "contagious" in the sense that it can be transmitted?
Yes. Apart from Tasmanian devils which are affected by the contagious cancer known as DFTD, or Devil Facial Tumour Disease, dogs and Syrian masters can also be affected by contagious cancers. CTVT, or Canine Transmissible Venereal Tumour is a venereal cancer in dogs which is spread during mating. Then there is the Contagious reticulum sarcoma cell cancer which is transmissible between Syrian hamsters by the bite of the Aedes Aegypti. This cancer was artificially created by scientists.
Together, colon and rectal cancers account for 10% of cancers in men and 11% of cancers in women
No. Mouth cancer is often the result of a chronic habit/addiction, such as chewing tobacco or smoking a pipe (although some mouth cancers arise spontaneously). Cancers, however, are not communicable from person to person.
Viruses are difficult to observe, cancers do not seem to contagious, cancer may develop long after the infection, and most viral particles can infect cells without inducing cancer.
This is not a contagious disease.The virus is contagious.
No. Mareks Disease is a highly contagious viral disease that produces cancers i chickens. Lim paralysis is the most obvious sign/symptom of Marek's. It is NOT a virus that will infect humans. It is limited to the poultry industry.
No, cancer is not contagious. It cannot be caught, and is not an infectious disease. Cancers develop within a particular person when their cell cycle is not controlled properly, or they have been exposed to carcinogens (cancer-causing substances).
No, it is not contagious.
All cancers can be prevented!
