Lung Cancer Symptoms in Women: What's Often Missed

Yes, and this is especially relevant for women. In Asia, more than 30% of lung cancer patients are never-smokers, and roughly 50% of lung cancer in women occurs in never-smokers. In India, the ICMR has formally acknowledged a steep rise in cases of lung cancer among non-smoking women in polluted cities. Lung cancer is among the top five cancers affecting Indian women. If you have persistent symptoms, being a non-smoker is not a reason to skip investigation.

Yes. Persistent shoulder, upper back, or scapular pain that is not clearly explained by injury can be an early sign. The cause can be peripheral and apical (upper) lung tumours. This includes Pancoast tumours. These can irritate nerves, muscles, and bone structures around the shoulder, scapula, and arm. This presentation is often initially treated as a frozen shoulder or muscular strain. Lung causes are only investigated later. Scottish Referral Guidelines explicitly list persistent chest or shoulder pain as a trigger. It can prompt an urgent chest X-ray. If shoulder pain has lasted more than 3 weeks without a clear injury explanation, raising lung causes with a doctor is reasonable.

Several reasons overlap. Biologically, women more often develop adenocarcinoma in the peripheral parts of the lungs. These can grow more silently before producing dramatic chest symptoms. Culturally, lung cancer is widely assumed to be a smoker's disease4. That applies disproportionately to men. Non-smoking women's symptoms are therefore less likely to be investigated for lung cancer early. Women also tend to deprioritise their own symptoms in favour of caregiving responsibilities. In India, roughly 50% of female lung cancer cases are already at advanced stage by diagnosis. This is the single biggest reason survival is lower than it needs to be.

Rarely as a standalone finding. But fatigue was one of the most common early symptoms in the MRC Lung Cancer Working Party study of more than 650 patients. It is also in the NICE NG12 symptom list. In adults over 40, fatigue should prompt consideration of a chest X-ray, mainly when combined with other unexplained symptoms. If fatigue has lasted for weeks, is out of proportion to activity, and has no clear explanation, raising it with a doctor is reasonable. Especially if you also have any of the other symptoms described in this piece.
