We will discuss in this topic that Which cancer causes the most deaths . First we start this topic we should know about cancer that What is cancer , Basically cancer is the uncontrolled division of abnormal cells, this is called cancer. We can say also tumor. According to the recent research of scientists in 2021 more then 20 million cases of cancer registered. And According the new research of scientists Globally 18.1 million patient of cancer registered.
(Which cancer causes the most deaths). The specialist of cancer is know as Oncologist. There are many types of cancer like Lungs cancer , blood cancer , and others. Now these days the most spread cancer is Breast cancer in Women , But we are going to discuss the major these two cancer and their symptoms and treatment.
BLOOD CANCER (Leukemia)
The exact cause of leukemia is unknown. A combination of genetic factors and environmental factors are believed to play a role. Risk factors include smoking, ionizing radiation, some chemicals (such as benzene), prior chemotherapy, and Down syndrome. People with a family history of leukemia are also at higher risk. There are four main types of leukemia—acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia as well as a number of less common types. Leukemias and lymphomas both belong to a broader group of tumors that affect the blood, bone marrow, and lymphoid system, known as tumors of the hematopoietic and lymphoid tissues.
- Fever or chills.
- Persistent fatigue, weakness.
- Frequent or severe infections.
- Losing weight without trying.
- Swollen lymph nodes, enlarged liver or spleen.
- Easy bleeding or bruising.
- Recurrent nosebleeds.
- Tiny red spots in your skin (petechiae)
Treatment may involve some combination of chemotherapy, radiation therapy, targeted therapy, and bone marrow transplant, in addition to supportive care and palliative care as needed. Certain types of leukemia may be managed with watchful waiting. The success of treatment depends on the type of leukemia and the age of the person. Outcomes have improved in the developed world. Five-year survival rate is 65% in the United States. In children under 15 in first-world countries, the five-year survival rate is greater than 60% or even 90%, depending on the type of leukemia. In children with acute leukemia who are cancer-free after five years, the cancer is unlikely to return.
It is the most common type of cancer in children, with three-quarters of leukemia cases in children being the acute lymphoblastic type. However, over 90% of all leukemias are diagnosed in adults, with CLL and AML being most common in adults. It occurs more commonly in the developed world.
LUNGS CANCER (lung carcinoma)
Lungs cancer is also know as lung carcinoma. Lung cancer is cancer that forms in tissues of the lung, usually in the cells that line the air passages. It is the leading cause of cancer death in both men and women. We are not wrong if we say this is most dangerous cancer that cause the most deaths in the world. There are two main types: small cell lung cancer and non-small cell lung cancer. These two types grow differently and are treated differently. Lung carcinomas derive from transformed, malignant cells that originate as epithelial cells, or from tissues composed of epithelial cells. Other lung cancers, such as the rare sarcomas of the lung, are generated by the malignant transformation of connective tissues (i.e. nerve, fat, muscle, bone), which arise from mesenchymal cells. Lymphomas and melanomas (from lymphoid and melanocyte cell lineages) can also rarely result in lung cancer.
In the US, both black men and black women have a higher incidence. The lifetime risk of developing lung cancer is 8% in men and 6% in women. Also in the US, military veterans have a 25–50% higher rate of lung cancer primarily due to higher rates of smoking. During World War II and the Korean War, asbestos also played a role, and Agent Orange may have caused some problems during the Vietnam War.
The vast majority (85%) of cases of lung cancer are due to long-term tobacco smoking. About 10–15% of cases occur in people who have never smoked. These cases are often caused by a combination of genetic factors and exposure to radon gas, asbestos, second-hand smoke, or other forms of air pollution. Lung cancer may be seen on chest radiographs and computed tomography (CT) scans. The diagnosis is confirmed by biopsy, which is usually performed by bronchoscopy or CT-guidance.
- a cough that doesn’t go away after 2 or 3 weeks.
- a long-standing cough that gets worse.
- chest infections that keep coming back.
- coughing up blood.
- an ache or pain when breathing or coughing.
- persistent breathlessness.
- persistent tiredness or lack of energy.
The major method of prevention is the avoidance of risk factors, including smoking and air pollution. Treatment and long-term outcomes depend on the type of cancer, the stage (degree of spread), and the person’s overall health. Most cases are not curable. Common treatments include surgery, chemotherapy, and radiotherapy. NSCLC is sometimes treated with surgery, whereas SCLC usually responds better to chemotherapy and radiotherapy. Worldwide in 2020, lung cancer occurred in 2.2 million people and resulted in 1.8 million deaths. It is the most common cause of cancer-related death in both men and women. The most common age at diagnosis is 70 years. In most countries the five-year survival rate is around 10 to 20%, while in Japan it is 33%, in Israel 27%, and in the Republic of Korea 25%. Outcomes typically are worse in the developing world.
