It is considered a significant risk factor in the development of penile cancer (odds ratio of 38–65). [9] Phimosis may also be a symptom of penile cancer. [18] Paraphimosis—Paraphimosis is a medical condition where the foreskin becomes trapped behind the glans. It is considered a risk factor for the development of penile cancer. [7]
Cancer slope factors (CSF) are used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit, on the increased cancer risk from a lifetime exposure to an agent by ingestion or inhalation.
Human penis with visible smegma behind the glans. In males, smegma helps keep the glans moist and facilitates sexual intercourse by acting as a lubricant. [7] [8] [9] Smegma was originally thought to be produced by sebaceous glands near the frenulum called Tyson's glands; however, subsequent studies have failed to find these glands. [10]
Among all primates, the human penis is the largest in girth, but is comparable to the chimpanzee penis and the penises of certain other primates in length. [13] Penis size is affected by genetics, but also by environmental factors such as fertility medications [14] [unreliable medical source?] and chemical/pollution exposure.
After treatment with white button mushroom extract in mice and patients with prostate cancer, scientists discovered a decline in the amount of immune-suppressing cells in tumors.
Carcinogens are defined as 'a substance or agent that can cause cells to become cancerous by altering their genetic structure so that they multiply continuously and become malignant'. [1] The World Health Organization breaks down the three types of carcinogens that can cause cancer in humans. The first type of carcinogen is the physical type ...
The probability of contracting a cancerous development depends on age, ethnicity and the existence, or non-existence, of environmental causation. Unlike all other genitally situated cancers, the incidence of penis cancer is related to the sexual mode of transmission. [3]
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
