Smoking women and cancer
Every woman heart how dangerous is smoking but still women continue to smoke. There is a list of diseases triggered by smoking but most dangerous are different types of cancer. Do you know that smoking can cause the following types of cancer in your body?
Smoking women and Cervical Cancer
Several studies identified the nicotine in the cervical mucous of smoking women. It was discovered that some chemicals found in cervical tissue are similar to tobacco chemicals. It was suggested that tobacco chemical could weaken the ability of cervical cells to fight off infection and may create a potential breeding ground for abnormal cervical cells to multiply.
You should know that nicotine in cervical tissues makes your cervix more susceptible to cervical cancer.
Stop smoking – prevent cancer
Scientists from different countries confirm that smoking could lead to the development of cervical cancer (4-5 times more often than in healthy non-smoking women).
During last decades it was proved that cervical cancer is caused by several types of the Human Papilloma Virus (HPV). Healthy women who do contract HPV, nearly 90% will clear the virus out of their body by their own immune system within 2 years.
Modern scientists suggest that smoking women are more likely to get cervical cancer if they become infected with HPV than are non-smoking women. Unfortunately the cervical tissue of smoking women is very receptive to HPV and chances of cervical cancer are much higher. Nicotine is actually found to promote cancer cell growth in cervical tissue. At the same time the nicotine found in the cervical mucous promotes the growth and spread of the cancer.
Health providers noted that smoking women with cervical cancer could have increased chances for remission and survival if they quit smoking.
It is well known that annual Pap-test is recommended for all women but for smoking women Pap-test is absolutely necessary test for cervical cancer prevention.
Smoking women and Breast Cancer
It is well known that tobacco smoke contains several known cancer-causing substances. The American Cancer Society published the results of a study in 1994 which indicated that breast cancer patients who smoke may increase their risk of dying at least 25% – a risk that increases with the number of cigarettes smokes per day. The possible risk of fatal breast cancer rises up to 75% for women who smoke two packs or more per day.
Scientific studies show that:
- Early smoking (during adolescent period) could raise women’s risk of developing breast cancer. Breast cancer risk is higher in women who start smoking before age 17.
- Smoking before menopause (especially before having children) could also increase the risk of breast cancer.
- Breast cancer risk is higher among heavy female smokers (25 or more cigarettes per day) and among current and past smokers with a history of 20 or more pack-years (number of packs of cigarettes smoked per day multiplied by the number of years smoked).
- Breast cancer risk is higher in women who had smoked for at least 20 years.
The good news is that if you quit now your potential risk of dying as a result of future breast cancer remains the same as for a non-smoking women.
Smoking women and Vulvar Cancer
Unfortunately the vulval cancer is also happening more frequently in smoking women. Scientists suggested that the main reason for it could be toxic reactions from tobacco elements.
There are several risk factors for vulvar cancer but non-smoking women get this type of cancer pretty rare. Smoking exposes the women body to many cancer-causing chemicals. Smoking women are more sensitive to risk factors and smoking women have higher chances to get the dangerous disease. Smoking increases the risk of developing vulvar cancer.
If women are infected with a high-risk HPV, they have a much higher risk of developing vulvar cancer if they smoke.
Smoking women and Skin Cancer
Smoking linked to skin cancer in women – the recent study has found a link between tobacco use and skin cancer. Women who smoked at least 20 years are twice more likely to develop very specific less aggressive form of skin cancer than melanoma – so called “squamous cell skin cancer”. Squamous cell cancer occurs in the epidermis, the top layer of skin, and can spread to other organs.
Researchers found that the more women smoked, the more likely they were to have skin cancer. Despite the elevated smoking related risk among women, men overall are more likely to get skin cancer.
Smoking women and Lung Cancer
Smoking women run a far higher risk of developing lung cancer than men – for each cigarette smoked, the danger is twice as high for women. Scientists suggested that the female sex hormone oestrogen could make women more vulnerable. The hormone puts women at greater risk of other kinds of cancer (mainly breast cancer), but it may also act in combination with cancer-causing environmental and risk factors.
According to research studies, it was revealed that a gene that fuels lung cancer growth is more active in women than in men – putting them more at risk of developing the lung cancer earlier and after smoking fewer cigarettes.
Smoking women and Bladder Cancer
Smoking is a risk factor for bladder cancer – cigarette smoking implicates in half of bladder cancers in women.
According to the report published by National Cancer Institute (NCI) in the Journal of the American Medical Association on 16 August 2011, current cigarette smokers have a higher risk of bladder cancer than previously reported, and the risk in women is now comparable to that in men. While previous studies showed that only 20 to 30 percent of bladder cancer cases in women were caused by smoking, these new data indicate that smoking is responsible for about half of female bladder cancer cases.
Scientists suggested that the increase in the proportion of smoking-attributable bladder cancer cases among women may be a result of the increased prevalence of smoking by women.
The researchers found that although there have been reductions in the concentrations of tar and nicotine in cigarette smoke, there have been apparent increases in the concentrations of certain carcinogens associated with bladder cancer.
In the current study, former smokers were twice as likely to develop bladder cancer as never smokers, and current smokers were four times more likely than those who never smoked. As with many other smoking-related cancers, smoking cessation was associated with reduced bladder cancer risk. Participants who had been smoke-free for at least 10 years had a lower incidence of bladder cancer compared to those who quit for shorter periods of time or who still smoked.
