The number of cancer patients diagnosed worldwide in 2020 reached 19.3 million, and the number of cancer deaths increased to 10 million, according to WHO data. People have never stopped exploring cancer treatments, but there are still many questions that have not been answered exactly. One of them is whether a weak immune system can cause cancer?
Content Highlights:
1. How does a weak immune system cause cancer?
2. How does cancer treatment affect the immune system?
Immunity is low and cannot recognize cancer cells, then these mutated “bad cells” will become bigger and stronger, so they have strength and become a prince, cancer will completely form and begin to threaten people of health.
Then, if the immunity is high, the Have cancer? Not too! If the immunity is high, there will be a lot of overreaction, then the tumor will take advantage of the chaos to revolt, separate one side, and threaten the human body.
So, the immunity is too strong Weakness is not good, only to avoid imbalance and maintain balance is the best.
In fact, tumor cells are produced every day in the human body, there may be more than 1 million, but the innate immune system will form a defense and protection mechanism, this system is like an army in the body, It can identify cells that are not good for the body, destroy and remove them at any time. If the immune function is abnormal, the system cannot recognize malignant cells. Over time, these cells will increase and eventually form tumors.
The immune system is the body’s defense against external bacteria, viruses, other Microorganisms, the system for normal immune response. Some people are born with a weak immune system. On the other hand, as the body ages, the immune system gradually weakens. In daily life, some unhealthy living habits will also affect the function of the human immune system, including: eating disorders, lack of sleep, nutritional deficiencies, too much stress, smoking and drinking, etc.
1 How does a weak immune system cause cancer?
When normal cells mutate to form cancer cells, the normal immune system of the human body will immediately initiate an immune response to rapidly displace cancer cells. Cells are cleared to prevent the occurrence of cancer, thereby maintaining the stability of the body itself. When there is a serious defect or lack of human immunity, cancer will occur. In the early stage, the human body cannot kill the cancer cells that have just started to develop in time, resulting in the continuous development of the tumor. The process of tumor metastasis is also related to various immune factors in the human body.
2How does cancer treatment affect the immune system?
Chemotherapy: Chemotherapy kills rapidly growing cells, including cancer cells and bone marrow cells. Damage to the bone marrow means it cannot produce disease-fighting immune system cells. May cause low white blood cell counts (neutropenia).
Radiation therapy: Radiation damages cellular DNA. This kills cancer but damages immune system cells. The effects are usually milder than chemotherapy, but also less predictable. Immune system damage may be direct or caused by radiation complications.
After chemotherapy and radiation, your immune system can maintain suppressed for several months. A study of breast cancer patients treated with chemotherapy found that the immune system often took 9 months or more to fully recover. Several types of immune system cells are depleted.
70% of the immunity in the human body comes from the gut. After a series of treatments, the patient’s body is very weak, and the body does not recover much after supplementing nutrition, that is, the gut does not absorb it. Nutrients, but also increase the number of harmful bacteria, it is easy to backfire. To solve this problem from the “root”, it is necessary to bring the intestinal microecology into a balanced state and restore the ratio of beneficial bacteria to normal. Bacteroides fragilis BF839 helps make up for the lack of human DNA. It can release anti-inflammatory substances, keep the immune system in balance, control the absorption and accumulation of toxins, and reshape the autoimmune microcirculation.
