A transmissible cancer is a cancer cell or cluster of cancer cells that can be transferred between individuals without the involvement of an infectious agent such as an oncovirus. [ 1 ] [ 2 ] The evolution of transmissible cancer has occurred naturally in other animal species, but human cancer transmission is rare. [ 2 ]
It is responsible for producing fluid that helps with sperm movement. Due to its location within the body, when diseased, it can affect the reproductive and urinary systems. [3] Prostate diseases, such as prostatitis, benign prostatic hyperplasia (BPH), and prostate cancer all affect the functioning of this gland. [9] [10]
Prostate cancer is a major topic of ongoing research. From 2016–2020, over $1.26 billion was invested in prostate cancer research, representing around 5% of global cancer research funds. [122] This places prostate cancer 10th among 18 common cancer types in funding per cancer death, and 9th in funding per disability-adjusted life year lost. [123]
Prostate cancer is a form of cancer that is typically slow-growing and originates in or on the prostate, a male reproductive gland that surrounds the urethra in proximity of the bladder and rectum. This is a result of malignant cells forming and multiplying at the prostate, which can then spread or metastasize to other organs in the body. [ 1 ]
There are several reasons why PIN is the most likely prostate cancer precursor. [3] PIN is more common in men with prostate cancer. High grade PIN can be found in 85 to 100% of radical prostatectomy specimens, [4] nearby or even in connection with prostate cancer. It tends to occur in the peripheral zone of the prostate.
A digital rectal examination and the measurement of a prostate-specific antigen (PSA) level are usually the first investigations done to check for prostate cancer. PSA values are difficult to interpret, because a high value might be present in a person without cancer, and a low value can be present in someone with cancer. [28]
The Shope papilloma virus (SPV), also known as cottontail rabbit papilloma virus (CRPV) or Kappapapillomavirus 2, is a papillomavirus which infects certain leporids, causing keratinous carcinomas resembling horns, typically on or near the animal's head. The carcinomas can metastasize or become large enough to interfere with the host's ability ...
Pyometra, uterine cancer, ovarian cancer, and testicular cancer are prevented, as the susceptible organs are removed, though stump pyometra may still occur in spayed females. Pyometra (or a pus filled womb) ('Pyo' = pus; 'metra' = uterus or womb) is a life-threatening condition that requires emergency veterinary treatment.
