At what age does leukemia usually develop? What are the characteristics of a person with leukemia?

1. Onset of leukemia is acute or slow, and many children and adolescents have a sudden onset. Common presenting symptoms include fever, progressive anemia, significant bleeding tendency, or bone and joint pain.

The onset of the disease is mostly elderly and some young patients, and the disease progresses gradually. Most of these patients have progressive fatigue and weakness, paleness, palpitation after exertion, shortness of breath, lack of appetite, weight loss, or unexplained fever as the first symptoms. In addition, a small number of patients may have convulsions, blindness, toothache, swollen gums, pericardial effusion, and paraplegia of both lower limbs as the first symptoms.

2. Fever and infection.

a. Fever is one of the most common symptoms of leukemia, which can occur in different stages of re-disease and have different degrees of fever and fever type. The main cause of fever is infection, among which angina, stomatitis, and perianitis are the most common, and pneumonia, tonsillitis, gingivitis, and perianal abscess are also more common. Ear inflammation, enteritis, carbuncles, pyelonephritis, etc. can also be seen, and severe infections can also occur with sepsis, sepsis, etc.

b. The pathogen of infection is mostly bacteria, and in the early stage of the disease, gram-positive cocci are the main pathogens. Viral infections are rare but often more sinister, and CMV, measles, or varicella virus infections are prone to pneumonia.

c. Bleeding Bleeding is also a common symptom of leukemia, the bleeding site can be all over the body, with **, gums, nasal bleeding being the most common, but also retina, intraauricular bleeding and intracranial, gastrointestinal, respiratory tract and other visceral hemorrhage. Menorrhagia is also common in women and can be the first symptom.

d. Anemia can appear in the early stages, and a small number of cases can develop refractory anemia months or years before diagnosis, and then develop into leukemia. Patients are often accompanied by symptoms such as fatigue, pallor, palpitations, shortness of breath, and edema of the lower limbs. Anemia can be seen in all types of leukemia, but it is more common in elderly patients, and many patients often have anemia as the first symptom.

In children and adolescents, acute manifestations include fever, infection, hemorrhage, anemia, thrombocytopenia on examination, markedly increased cells in the bone marrow, lymph nodes, hepatosplenomegaly, asymptomatic in the early chronic stage, fatigue, low-grade fever, hyperhidrosis, weight loss.

People with a high incidence of leukemia and age groups.

Question 1: At what age does leukemia occur? The incidence of leukemia, especially in the elderly, is relatively high.

Myeloid leukemia can occur in adolescents, children, middle-aged to elderly people, but it is slightly higher in middle-aged and elderly people. Unlike chronic lymphocytic leukemia, children will not have it. Cause of occurrence:

Viral, chemical, genetic, other blood disorders.

Question 2: How does leukemia occur and at what age does it occur? The incidence of chronic lympholeukemia, especially in the elderly, is relatively high.

Myeloid leukemia can occur in adolescents, children, middle-aged to elderly people, but it is slightly higher in middle-aged and elderly people. Unlike chronic lymphocytic leukemia, children do not have to travel there.

Causes: Virus, Chemistry, Genetics, Other Blood Disorders.

Question 3: At what age does leukemia occur? There is no such statement, leukemia is hereditary, it is born!

Some are exposed to certain anti-tumor cytotoxic drugs, such as nitrogen mustard, cyclophosphamide, methylbenzylhydrazine, VP16, VM26, etc., which are recognized to have leukemia-causing effects. Some of them are caused by radiation, and there is conclusive evidence that various ionizing radiation conditions can cause human key car pin leukemia. There is also a kind of animal contact with RNA tumor virus!

So leukemia doesn't say how much it happens at what age! No matter what age you are, as long as the above situation happens to you, then you may get leukemia!

Hello, generally speaking, pediatric leukemia is dominated by acute leukemia, accounting for 35% of the total number of acute leukemia in all age groups, and is most common in 2-5 years old, of which acute lymphoblastic leukemia accounts for 70%-85%, acute non-lymphocytic leukemia accounts for 15%-30%, and the high incidence of acute lymphoblastic leukemia is the pathogenesis characteristic of childhood leukemia. But please don't worry, you can take a look at (cancerous heart road Han Qi) If you want to develop in medicine, leukemia is completely possible.

Hello. Words in this regard. Not necessarily.

The age of onset of different types of leukemia is different The total incidence in China is 10,000, and acute leukemia is more common than chronic leukocytes, of which acute non-lymphoid leukemia is the most, followed by acute lymphoid leukemia and chronic myeloid leukemia, and chronic lymphoid leukemia is the least. can be improved by relying on (cancerous heart path Qi Feng).

I often work in the chemical chief, I am contaminated by radiation, I can't use drugs, I eat indiscriminately, and I often love to eat too much snake python.

Why do you get leukemia? Who is more likely to get leukemia?

First of all, leukemia is a malignant clonal disease of hematopoietic stem cells, in which the proliferation of leukemia cells in the clones is uncontrolled and differentiation is impaired.

**Viral factors, chemical factors, radiation factors, genetic factors, acute leukemia is more common in children and adolescents.

In chronic leukemia, the incidence of chronic leukemia increases with age, and the incidence of chronic leukemia increases with age, and the incidence of chronic leukemia is more common after the age of 50, but acute leukemia is much more common than chronic leukemia.

Therefore, most of the people who get leukemia are children and adolescents.

Do you have leukemia so worried about yourself? Just tell me how old you are...

Hello, the incidence of hereditary diseases is 150 times higher than that of offspring born of non-consanguineous marriages, these children often have chromosomal mutations, so they are more likely to get leukemia, as well as long-term contact with gasoline, long-term exposure to hair dyes, or those who have been exposed to radiation, clinical patients report (Qi Feng's acute cancerous heartway) can increase immunity and resistance.
