There are a number of connections between breast and cervical cancer. Most patients affected with breast cancer are women, and all cervical cancer patients are female. Women are routinely screened for both of these types of cancer in the hopes that an early diagnosis will allow for more effective treatment. Some risk factors, such as prolonged oral contraceptive use and smoking, are considered to increase the likelihood of developing these cancers. A rare disease called Peutz-Jeghers syndrome can cause both types of cancer in some affected women.

The clearest connection between these cancers is that they are diseases primarily seen in women. Cervical cancer is only seen in females. Breast cancer, although much more common in women, can still affect men because they have small amounts of breast tissue under their nipples. Male breast cancer represents less than 2 percent of all diagnosed breast cancers.

Breast and cervical cancer are also linked because women are regularly screened for the development of these two diseases. Cervical cancer screening is performed by swabbing the cervix and doing a Papanicolaou (Pap) smear on the cervical cells obtained from the swab; this diagnostic test checks for the presence of abnormal cells that could represent cancer. Women should be screened with a Pap smear every one to two years depending on their ages and risk factors. Breast cancer screening typically employs the use of mammography, an imaging study that evaluates the breast tissue and looks for abnormal growths. Most women should receive yearly mammograms after the age of 40, although some experts recommend that women could wait until they are 50 years old to begin having regular mammograms.

One less well known connection between breast and cervical cancer is that oral contraceptive pills can increase the risk for both types of malignancies. It is thought that the extra hormones provided by this medication can promote the growth of abnormal tissue that can become cancer. Overall, however, the increased cancer risk caused by oral contraceptive pills is small, and many women can safely take these medications.

Smoking could be considered another risk factor that is common to both breast and cervical cancer. Although the most important risk factor for cervical cancer is infection with the human papillomavirus (HPV), smoking is another known risk factor for the development of the disease. Some researchers argue that smoking also increases the risk for breast cancer.

A more obscure connection between breast and cervical cancer is that both can be seen in a genetic condition called Peutz-Jeghers syndrome. This condition develops due to a genetic mutation that puts patients at increased risk for developing tumors. Although the most common complications of Peutz-Jeghers syndrome include having spots of abnormally pigmented skin and developing benign gastrointestinal growths, some affected patients can develop both breast and cervical cancer over the course of their lives.

@bluedolphin-- I'm not sure about breast cancer, but cervical cancer does have some symptoms like bleeding, pain during sex, discharge, etc. So if women experience any of these, it's important to see a doctor right away.

For the most part, I think it's still rare for women to get these cancers in their twenties and thirties. But rare doesn't mean impossible so it's important to know for the symptoms to look out for. Women can also check for breast cancer at home themselves by checking their breasts for lumps.

I do agree with you that cancer in general, whether it's breast cancer or cervical cancer, seems to be on the rise. And I think it partly has to do with our stressful lifestyles, lack of exercise and poor diet. Foods have also become very unhealthy, full of chemicals and preservatives these days.

I know two people who have gotten these cancers at a young age, in their thirties. One is an acquaintance who got cervical cancer at age 36. One is a friend who got breast cancer when she was only 28.

So I wonder if it's a good idea for women to start getting tested for these after they're 40 or 50. I think the age of cancer may be getting younger and younger.

Smoking increases the risk of any kind of cancer. But aside from this and other general unhealthy habits, I don't think that there is a very strong connection between breast cancer and cervical cancer. I think this way because most cases of cervical cancer are due to the human papilloma virus (HPV). This virus affects the cervix directly. The cause of breast cancer isn't HPV.

Perhaps, some people may have a genetic inclination towards cancer or there may be risk factors like smoking, etc. But that's probably about it. Having said that, I'm not an expert on this topic and I would love to hear opposing views. I could be wrong.
