John	Usually it runs like this... primary tumor - when cancer cells reach, and then break through lymphatic system ( lymphatic node close to tumor becomes swollen ) they get into bloodstream.. There it can travels everywhere..brain, colon, medulla...

Ika	Tumor can grow swiftly if steps into malignant tumor category. tumor menjalar kesegala body organ can, because food which we eat. every when food which we eat is poison or garbage. we eating food ready stock (fast food), what can trigger the cholesterol and cancer cells in our body. vegetables which we eat also can cause cancer since have already been hit peptisida and dirt. juices which we drink more than 8 hour also, has of no use, because fruit which have been cut or made juice and has more than 8 hour, be dregs because the vitamin in it has evaporated. and one of cancer cause apart from food is STRESS.

Robbie	When you have cancer in a certain part of your body (whether benign or malignant), the cells begin to replicate erratically. This causes the cells to get uneven and, when uneven, they tend to break off. They will travel through the bloodstream and the lymph nodes to the rest of the body. When the malfunctioning cells come into contact with healthy cells, the healthy cells will malfunction as well and start the process over. I hope this answer helps! -R

bigjohn B	The tumor keeps growing and pushes into the rest of the body. Pieces of the cancerous tissue can travel through the body and develop lesions elsewhere.

blues breaker	cells are very small and can metastasize anywhere. check the website for the american cancer society for beter info.

TheAimer	in laymans terms, cancer cells break off of a tumor and travel to other parts of the body through the bloodstream. Tumors caught in early stages without metastisizing have a better chance of being eradicated without return...thats why its so important to get a checkup and get things checked out when things are not right...

SPD-WRLDS	cancer can start on certain area of the body where damaged cells have started to grow out of control and form a tumor and then it spreads through the blood stream and start to form tumors elsewhere like the brain lymph nodes and other areas of body and usualy it grows faster. if cancer is the small cell it is the fast growing and it can spred very quick and is very agressive type. hope this helps.
