Lifestyle and Reproductive Characteristics Among Women with Breast Cancer in Pakistan: A Cross- Sectional Study with Comparison to Western Evidence

Breast cancer is a disease that affects the tissue of the breast, and it remains the most frequently diagnosed cancer among women across the globe. While age is a major factor in who develops the disease, with risk generally increasing as women grow older, the specific reasons why some women get it while others do not are complex. Scientists look closely at lifestyle habits—such as what people eat, how much they move, and whether they smoke—as well as reproductive history, including when a woman has her first child and whether she breastfeeds. These are known as modifiable factors because, unlike age or genetics, people can change them. Understanding these patterns is vital for public health, as it helps doctors and communities design better ways to prevent the disease or catch it early. However, what works in one part of the world does not always apply to another, and the unique cultural and social environment of a region can shape how these risk factors play out.

In Pakistan, breast cancer is a significant health concern, appearing more frequently there than in neighboring countries. A notable feature of the disease in this region is that it often strikes women at a younger age compared to Western nations. To understand the landscape of this disease in Pakistan, a team of researchers at the Rehman Medical Institute in Peshawar conducted a study focused on the daily lives and medical histories of women diagnosed with breast cancer. They wanted to see what common traits these women shared, particularly looking at whether these traits differed between younger women, defined as those under forty, and older women, those forty and above. The goal was not to prove that a specific habit caused the cancer, but rather to paint a clear picture of the characteristics present in this specific group of patients, providing a foundation for future research and local health strategies.

The researchers gathered information from eighty-five women who had been confirmed to have breast cancer through a biopsy. They interviewed each woman and reviewed her medical records to collect details about her body weight, physical activity, smoking habits, diet, and reproductive history. The team divided the participants into two groups: twenty-seven women who were younger than forty and fifty-eight women who were forty or older. They then looked for patterns in how these women lived their lives. The study found that being overweight was very common; nearly half of the women fell into the overweight category, and about fifteen percent were classified as obese. Furthermore, a majority of the women reported leading a sedentary lifestyle, meaning they did very little physical activity in their daily routines.

When the researchers compared the younger women to the older ones, they found that the distribution of these lifestyle factors was surprisingly similar. The proportion of women who were overweight or obese did not differ significantly between the two age groups. Similarly, the lack of physical activity was common in both groups, with slightly more older women reporting a sedentary routine, but the difference was not large enough to be considered a distinct pattern. The study also examined reproductive history, such as whether a woman had given birth and at what age. About twenty-eight percent of the women had never given birth, a condition known as nulliparity. While this was slightly more common in the younger group, the difference was not statistically significant. Most women in the study had their first pregnancy before the age of thirty-five, and more than half reported breastfeeding their children for over six months.

The researchers also looked at habits that are often linked to cancer in other parts of the world, such as smoking and the use of birth control pills. In this group of Pakistani women, these factors were relatively rare. Only a small number of women were active smokers, and even fewer reported exposure to secondhand smoke. Similarly, fewer than twenty percent of the women had used oral contraceptive pills. This stood in contrast to findings from Western countries, where smoking and hormone use are more frequently discussed as risk factors. The study also highlighted a critical issue regarding timing: a large majority of the women, nearly sixty-four percent, had experienced symptoms for six months or longer before they finally sought medical help. This delay in seeking care was a consistent finding across the group, suggesting that barriers to early detection are a significant challenge in this region.

The authors of the study were careful to note what their findings could and could not prove. Because the study only included women who already had breast cancer and did not include a group of healthy women for comparison, they could not say for certain that being overweight or inactive caused the cancer. Instead, the study serves as a detailed description of the women who were affected. It shows that in this specific community, the disease is often found in women who are younger than the typical screening age, and that these women frequently share characteristics like excess weight, low physical activity, and a significant delay in seeking medical attention. The low rates of smoking and oral contraceptive use suggest that the risk factors driving the disease in Pakistan may differ from those in the West.

This research provides a crucial snapshot of the reality of breast cancer in Peshawar. It moves beyond general assumptions to offer concrete data about the lives of the women affected. The findings suggest that public health efforts in this area might need to focus differently than in other parts of the world. Rather than focusing heavily on smoking cessation or hormonal factors, which were uncommon in this group, the data points toward the need to address obesity, encourage physical activity, and, most urgently, improve awareness so that women seek help sooner after noticing symptoms. By understanding these specific local patterns, health officials can begin to tailor their prevention and detection strategies to fit the actual needs of the Pakistani population, potentially saving lives through earlier intervention and more relevant health education.
