Is late-stage lymphoma contagious?

Lymphoma is a malignant tumor originating from the lymphatic hematopoietic system. It is mainly manifested by painless lymphadenopathy, hepatosplenomegaly, and all tissues and organs of the body may be affected, accompanied by systemic symptoms such as fever, night sweats, weight loss, and itching. Is lymphoma contagious? Lymphoma, also known as "lymphoma", is one of the ten most common malignant tumors in China. So is lymphoma contagious? Let's take a look at what experts say.

Is lymphoma contagious in late stages? Experts say that lymphoma is caused by factors such as people's long-term unreasonable diet structure and irregular living habits, which lead to excessive acidification of the body, a rapid decline in the overall function of the human body, stagnation of blood and qi, and a large amount of acidic waste produced by the body. So far, medicine believes that cancer is not contagious. The so-called contagion, in simple terms, is the spread of a disease from one person to another through some means. Contagion must meet three conditions: the source of infection, the route of transmission and the susceptible population, none of which can be missing.

Experts have conducted experiments in which cancerous tissues removed from cancer patients were directly implanted in another person, but they could not survive and grow. Although it is currently believed that the occurrence of certain cancers is related to certain viruses, it has not yet been confirmed that infection with certain viruses will definitely lead to certain cancers. Cancer cells in the patient's body are a group of abnormal cells that have lost control and grow in an invasive manner. It not only destroys adjacent normal tissues and organs, but can also transfer to all parts of the body through the lymphatic system and blood circulation, and absorb a large amount of nutrients, grow and proliferate rapidly, causing the patient's systemic failure and even death. Although cancer cells can spread or transfer everywhere in the patient's body, they will not be transmitted from one person to another like bacteria and viruses. To oneself, other people's cancer cells are a kind of foreign body, and the body destroys the cancer cells through its powerful immune rejection ability. Therefore, lymphoma is not contagious.

So what are the causes of lymphoma? Understanding the causes of lymphoma can help us better prevent and treat the disease. Let’s learn more about it below.

Causes of Lymphoma:

1. Immune factors Immune factors are one of the important causes of lymphoma. Under normal circumstances, the human immune system has an immune surveillance function and can clear mutated or cancerous cells in the body. Immunodeficient patients are prone to opportunistic infections, especially viral infections. In addition, low immune function such as AIDS, organ transplantation, rheumatoid arthritis, etc. can also induce lymphoma.

2. Viral etiology Viruses are an important direction in the study of tumor etiology. According to current research, the viruses that are more closely related to lymphoma include Epstein-Barr virus, human T-lymphotropic virus, and human B-lymphotropic virus.

3. Genetic factors There are many reports about the influence of genetic factors on lymphoma. Tumors themselves are not inherited. The inheritance of lymphoma refers to the quality of tumor occurrence. Some people's physical fitness is prone to cancer under the action of carcinogens, or they have low immunity to abnormal cells, which leads to lymphoma under the stimulation of external factors. Sometimes obvious family aggregation can be seen, such as brothers and sisters can suffer from lymphoma successively or at the same time.

4. Physical causes (radiation) The cause of lymphoma is not only related to the dose of absorbed radiation, but also to the age at the time of exposure. The incidence of lymphoma is higher in people under 25 years old exposed to radiation than in other groups. The impact of medical radiation on the incidence of human tumors has received increasing attention, especially high-dose radiation has a promoting effect on the occurrence of human lymphoma.

5. Chemical causes Chemical carcinogens include alkylating agents, polycyclic aromatic hydrocarbons, aromatic amine compounds, etc., which are certain causes of lymphoma. For example, excessive use of hair dyes by women can lead to lymphocyte cancer. In agricultural production, with the application of pesticides and fertilizers, the incidence and mortality of lymphoma in rural populations are also increasing.

6. Diet structure: With the change of modern diet structure, long-term acidic constitution is one of the causes of lymphoma. People should maintain good living habits and a reasonable diet in their daily lives. Especially those with family-clustered lymphoma should stay away from the causes of lymphoma, which can reduce the incidence of lymphoma to a certain extent.

Knowing the causes of lymphoma, we must develop good living habits in our daily lives to effectively prevent the occurrence of lymphoma.
