The path that the cancer spreads

The malignant tumor is in the process of growing in, the lump cell gradually arrives surroundings organization in the part, can also transfer other parts of body in the meantime.The part of malignant tumor cell gradually transfers and then is called proliferation of cancer with distance.Cancer proliferation is special malignant tumor property, and is the main reason that threatens sufferer's health and life, particularly tumor distance's transfering is a serious problem, about half cancer sufferers have been already transfered already while being confirmed.
Because the tumor grows up, the lump cell delivered part to constantly and gradually and around organize in a row at first and was called a directly spreading of the malignant tumor, was also part proliferation.If later period cervical cancer could spread the rectum and the urine bladder, later period lung cancer could infringe upon chest film and chest and have of even attain chest wall.
The malignant tumor all can follow organization cleft gradually, the cancer often invades toward the partial lymphoid tube smooth and growth, the cancer cell can be full of whole lymphoid tube, form solid sex of ivory Suo, be called a lymphoid tube to permeate;Tumor then often gradually small vein and the hair thin blood vessel, can also result in blood vessel's permeating.Can also take place chest, belly cavity and other chamber way gradually in addition.
Malignant tumor cell invade part lymph tube, afferent or other chamber way after, lump cell follow these tube the chamber is taken other parts and continue to breed to increase to living in the new part lump cell, formation with original hair the part same type of tumor, namely after hair tumor or transfer sex tumor.This process is called tumor to transfer.In addition to minority of malignant tumors such as the skin base cell cancer and some central nervous system system tumor seldom the occurrence transfers, the great majority malignant tumor can take place to transfer when the disease makes progress.The tumor had a few following paths while transfering:
(1)lymphoid way's transfering is more familiar than various cancer and invade the cancer cell of lymphoid tube to arrive first with the lymph part lymphoid knot, continuing to develop can transfer to close to or lymph knot in the distance.If the mammary glands cancer transfers to arrive side armpit lymph to together knot first, after can transfer lock bone bottom and lock bone ascend lymphoid knot, even to side armpit lymph knot.
(2)blood way's transfering is more familiar than a various tumor, endocrine cancer and didn't divide a cancer, directly invade blood vessel or through lymphoid tube again go into afferent lump cell to arrive other parts with the blood.It is lung, brain, liver and bone to transfer part most familiarly.The stomach and intestines way cancer often transfers to the liver and the lung, the mammary glands cancer, kidney cancer, and blood relationship lump...etc. often transfer lung, the lung cancer easily transfers to a brain, and the prostate gland cancer easily transfers to a bone.Plant to transfer the lump cell that sheds off from the tumor surface in planting of occurrences such as chest, belly cavity and brain spinal cord chamber etc. sex growth, because of gravity of cause, usually plant in the lower part of these cavities, like the rib Ge Cape, the rectum urine bladder nest, and Lu bottom...etc..
