Can cancer be passed on through sperm?
Secondly, a study in 1998 demonstrated that prostate-cancer cells can be found in semen, although not with enough specificity to serve as a diagnostic test. Still, that doesn’t mean that prostate-cancer cells carried in semen could spread cancer to another person.

What causes cancer to spread fast?
When cancer spreads in the body, it is first and foremost due to changes, or mutations, in the DNA of cells. Because of a mutation or other abnormality in a cancer cell’s genome (the DNA stored in its nucleus), the cell may become separated from its neighbors and invade surrounding tissue.
Who is prone to cancer?
Cancer can take decades to develop. That’s why most people diagnosed with cancer are 65 or older. While it’s more common in older adults, cancer isn’t exclusively an adult disease — cancer can be diagnosed at any age.
How do cancers spread?
When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.
