How does cancer spread?

Answer 1

Breast cancer CAN NOT be transmitted, just so you know . So , don't be scared , you can't get it nor can you give it to any one else.

the only way you can receive it is from your parents its a GENETIC disease

Answer 2

Cancer can be transmitted by a number of routes;

1. Local Invasion to the surrounding tissue.

2. Lymphatic spread, sometime cancer cell will move from the site of origin by lymphatic circulation to a distant regional lymph nodes.

3. Hematological spread, some forms of cancers can be transmitted from the original site to a distal location by the way of venous circulation.

4. During surgery, sometime cancer cells will spread to a remote place during surgery, either by direct contact to the tumor, contaminated instruments and gloves, or to the site of incision.

5. Kissing mode, this mode of transmission found when you have a direct contact withe the cancer itself, for example cancer in the lower lip may spread to the upper limb, or cancer in the labia majora may spread to other vicinity around the vulva.

6. Transcolonic spread, the best example for this type of cancer is Krukenberg cancer, which is a secondary ovarian tumor, it's primary site is usually adeno carcinoma of the stomach.

Answer 3

Cancer can spread through many different ways, first it spreads by not adhering to normal selection barriers. So when normal cells hit a selection barrier like the basal lamina or low oxygen they stop. Where as cancer cells do not. They stop but then they can proliferate until one of the cancer cells acquires a genetic mutation to go past that barrier. Cell death also goes along with proliferation of cells in cancer this is not the case.

Answer 4

Cancer is not caused by Bacteria, it is caused by normal cells changing in inappropriate ways.

Answer 5

some cancerous cells may breakaway from the tumor and enter the blood stream. which allows cancer to spread througt out the body.
