Cancer represents a group of illnesses consisting of more than 1000 conditions. This sickness affects basic unit in the body: the cell. It appears when cells start functioning abnormally and start splitting without order or limit. New mass is formed which is called tumor and it can be either benign or malignant. Benning tumors are not a cancer and their cells do not spread to other body parts. They rarely pose any health hazard. On the other hand, malignant tumors are cancer. From primary tumor, cells can reach other body parts by traveling in blood or lymph. This spreading causes metastasis of primary tumor. When breast cancer reaches metastasis, cells can appear in lymph knots. So, this means that disease has spread to other parts of the body, bones, liver or lungs. This kind of tumor retains same type of malignant cells as the primary tumor.
Histogenetic breast cancer can appear from primary atypical epithelium hyperplasia and from regular ductolobular epithelium. More than half of breast cancers appear in upper outer quadrant and sprouts of hormonal tissue. In area around nipples, that is in central part of breast, 15 to 20 percent of cancers appear. In lower region of breast, it will appear in 5 to 10 percent of cases. Usually, cancer will affect only one breast. Have in mind that cancer is more common for left one (for about 10 %). It is very rare for cancer to appear on both breast and in the same spots (1 to 6 % of cases). Breast tumor grows very slowly. It can pass from 6 to 8 years until tumor reaches diameter of 1 cm or if until becomes noticeable. One of the best ways of treating it is to buy Methotrexate online.
Doctors are still not sure what causes cancer in some individuals. Specialists from youdrugstore.com claim that it is very hard to establish impact of environment and genetics in development of the disease. Some of the risk factors which certainly contribute to development of the disease are: family history of the disease (especially if your mother had breast cancer before 40), women who already had this condition, exposure to radiotherapy before 30, breasts which are built from many ducts and have less fat tissue, existence of atypical hyperplasia, age of first menstruation as well as age when menopause started, total length of reproductive period, number of pregnancy and age when you had first baby, women who had baby after 30, higher exposure to estrogen, sensitivity during menopause, lack of physical activity, use of alcohol.
Have in mind that cancer still remains one of the worst medical conditions you can get. With the development of pharmacology, we have certain solutions such as Methotrexate. This drug prevents growth of certain cells, especially cancer cells. Besides cancer, it can also be used for psoriasis and rheumatoid arthritis. People who are allergic to this drug, who have bone marrow disorder, those who are breast-feeding a baby, individuals with cirrhosis or some other liver issue as well as those with blood cell disorder, should avoid this medicine.
