究竟lymphatic system係咪真係可以hinder the spread of cancer cell???

究竟lymphatic system係咪真係可以hinder the spread of cancer cell???

如果可以既話, 佢個process 係點?

t cell , b cell 會點去做野??

有冇d 真實既example??

eg: breast cancer 同 skin cancer佢地個spread 既過程係點??

o係blood 會係點? o係lymphatic system 會係點?? 詳細既過程係點?

    One of the body's defenses when it is under attack is circulating antibodies in the blood that latch on the antigens on the surface of the yeast cell. We are not talking about just one antigen and one antibody attached to it, per yeast cell. There can be literally hundreds of such pairs per yeast cell. Presence of such Ag-Ab pairs gets the complement systems going, and pretty soon the cell is coated with literally thousands of particles of complement. (Please read my previous article on "Complement (no typo) to your health" for background information on complement system and how it works).

    Cells which are covered by complement fragments are said to be "opsonized". Such cells are quickly killed. Phagocytic cells (cells that are literally capable of eating up other cells) such as macrophages and neutrophils are attracted to the site of the opsonized cells, and quickly eat them up. This is called the classic pathway by which complement attacks pathogens such as yeast cells.

    Tumor cells grow in the body in the first place because the body does not recognize them as "foreign and dangerous", as are yeast cells. Part of the problem is that tumor cells do not have a real ugly antigen on their surface that triggers activation of the immune system. If this were not the case, there would be sufficient home grown antibodies against the cancer cells, and the tumor would be killed before it had a chance to grow. The fact you have CLL says your body is not able to mount a sufficiently effective antibody response to the antigens on the tumor cells.

    OK. So we have CLL, but no antigen that the body recognizes, and therefore no antibody. Not to worry, IDEC comes to the rescue, we define CD20 marker on B-cells as an antigen, and make an antibody against it called Rituxan. Once this drug is administered to patients with CLL, especially those with a large percentage of b-cells that are positive for CD20, and have a large number of CD20 markers per cell, we have met the first condition for killing the cell. Namely, antigen-antibody complexes are formed on the surface of the cancer cells.

    唔好意思!只知道有只佰靈仙姬細胞修復液,能夠有顯著幫助,又或如末手術和化療前飲用都可,飲用幫助到回復癌細胞指數正常,甘唔使化療,如已正在化療中,覺得辛苦不適,更要飲佰靈仙姬,可以舒緩身體不適,提升免疫能力,對抗癌細胞。

    已化療完成後也可飲用,幫助清除異變細胞潛伏份子,幫助清除體內長期過高酸性,過高酸性是致病的原兇。唔系廣告。

    留電郵或賞分數,給你寶貴的資料。

    Immune system of the body can kill cancer cells to a certain extend. It can destroy the tumour cells by secreting tumour necrosis factors. It is a very complicated process. However, as cancer grows in the body, this means that immune system fails to kill all the tumour cells. Being a cirrculatory system, lymphatic system serves as a medium to transport cancer cells to other organs. I don't know whether you can say lymphatic system hinders the spread of cancer cells, but it is true that lymphatic system can protect body against the invasion of cancer cells as well as the spreading the cancer cells. Hope you understand this concept.
