Women are prone to Lung Cancer
Women Face Special Lung Cancer Risks
More than 20 years ago lung cancer surpassed breast cancer as the no. 1 cause of deaths in mowen, yet it remains a disease often overlooked in this population. In fact, lung cancer kills more women than breast cancer, ovarian, and even uterine cancer. It would be easy to attribute the rising numbers strictly to the increased smoking prevelence in younger women, more non smokers with ling cancer era women.
There are emerging evidences that suggests there may be specific sex differences in the genetic, biologic and hormonal factors contributing to women's increased incidence of lung cancer: a higher susceptibility to carcinogenic properties of cigarette smoke, higher levels of DNA adduct formation, decresed DNA lung cancer, vry in their treatment response and outcomes and have better survival rates than men.
Lung cancer cells can be either nonsmall cell lung cancer, which accounts for 80% of lung cancer cases, or small cell lung cancer. Nonsmall cell lung cancer includes squamous cell, adenocarcinoma, broncholoalveolar carinoma. a subtype of adenocarcinoma and large cell carcinoma.
Women vary from their male counterparts in both histologic distribution and treatment outcomes. Bronchioalveolar carcinoma presents more commonly in female smokers and nonsmokers of both sexes. Adenocarcinoma is more commonly seen in femaler smokers while male tend to develop squamous cell carcinoma. Nonsmokers who develop adenocarcinoma are 2.5 times more likely to be female. However the invcidence of large cell is more diffuse and agressive oin both sexes than small cell lung cancer.
When nonsmall cell lung cancer is diagnosed in its early stages, it can usually be successfully treated with surgery. Women are reported to have superior survival rates after surgical resection or radiation as a single treatment modality for stage 1 or stage 2 lung cancer. Local or regionally advanced nonsmall cell lung cancer is treated with radiation and chemotherapy. Patients with more advanced disease received a combination of chemotherapy agents. Women have demonstrated improved survival compared to men after chemotherapy for advanced stage 4 nonsmall cell lung cancer. Some patients may receive all three treatment options. (Surgical removal of tumor, Chemotherapy, and radiation therapy.
When I was about to read this article, i don't expect that women are prone with lung cancer. Even though they are smoker or nonsmoker they are still prone with this kind of disease. We women must be aware of the disease that we can acquire even though it was not expected at all.
Everythings happen for a reason.
