Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
In 2014 about 7,060 new cases of anal cancer were diagnosed in the United States (4,430 in women and 2,630 in men). [39] It is typically found in adults, average age early 60s. [39] In 2019, an estimated 8,300 adults will be diagnosed with anal cancer. [40] In the United States, an estimated 800 to 900 people die of anal cancer annually. [39]
The risk for anal cancer is 17 to 31 times higher among HIV-positive individuals who were coinfected with high-risk HPV, and 80 times higher for particularly HIV-positive men who have sex with men. [65] Anal Pap smear screening for anal cancer might benefit some subpopulations of men or women engaging in anal sex. [66]
Tumor-homing bacteria are facultative or obligate anaerobic bacteria (capable of producing ATP when oxygen is absent or is destroyed in normal oxygen levels) that are able to target cancerous cells in the body, suppress tumor growth and survive in the body for a long time even after the infection. When this type of bacteria is administered into ...

Fusobacterium is a genus of obligate anaerobic, Gram-negative, [2] non-sporeforming bacteria [3] belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends. [ 4 ] [ 5 ] Fusobacterium was discovered in 1900 by Courmont and Cade and is common in the flora of humans.
