why does it happen

Malignant neoplasm occurs due to uncontrolled and abnormal proliferation of malignant cells, which can happen due to DNA changes due to genetics or habits, such as smoking, nutritionally poor diet and rich in fried foods, consumption of alcoholic beverages, viral infections and exposure. to toxic substances or radiation, for example.

Malignant cells multiply quickly and can spread to other organs and tissues, as these cells have an autonomous behavior, characterizing metastasis, which makes treatment and cure more difficult to happen.

Regarding laboratory tests, the doctor may request a blood count and biochemical tests, in addition to the dosage of tumor markers, which are substances produced by the cells or by the tumor itself, indicating the presence of a malignant neoplasm. In addition, the doctor may request a histopathological examination, which aims to confirm the malignancy of the cells. Find out about the tests that identify cancer.

How is the treatment done?

Treatment for malignant neoplasm is done with the aim of decreasing the rate of proliferation of malignant cells, preventing metastasis and improving the person’s quality of life. Usually the doctor recommends surgery, radiotherapy or chemotherapy according to the type of neoplasm and its characteristics.

Surgery may be indicated in cases where metastasis has not yet occurred and where the tumor or part of it can be removed. However, in some cases surgery may not be indicated due to its location and blood supply at the site, and other treatments are indicated by the doctor. Generally, after surgery, chemotherapy or radiation therapy is recommended in order to eliminate any malignant cells that have not been removed.

Chemotherapy is the most recommended treatment in case of cancer and is done with the use of specific drugs against the tumor that can be administered orally or intravenously. Radiotherapy is also a treatment option for malignant neoplasms and consists of applying radiation to the tumor site, reducing its size and preventing it from spreading to other regions of the body.

Is malignant neoplasm curable?

It is possible to achieve a cure when the malignant neoplasm is identified early and treatment is started quickly, as it is possible to prevent metastasis, which is the spread of malignant cells to other parts of the body, which makes treatment difficult. Understand how metastasis happens.
