At 35, can my symptoms suggest lung cancer?

Question

Hello, Doctor,

I am 35 years old, and I have been having this dry cough for almost four months now that just won't go away, no matter what I do. I also noticed I get out of breath really quickly, even when climbing just one flight of stairs, which never happened to me before. I smoked for about 8 years, but quit two years back.

My general physician did a chest X-ray and said it looks slightly abnormal in the upper left lobe but didn't explain much. I have also been losing weight without trying, maybe six to seven kgs in the last three months. My CBC showed hemoglobin at 10.2, and my CRP is elevated. I know 35 seems young for lung cancer, but I read that it does happen. Some mornings, I cough up a little blood, which scares me a lot. My voice has also become slightly hoarse over the past few weeks. The respiratory specialist referred me for a PET scan, but the appointment is two weeks away. I don't want to panic, but I also don't want to miss something serious. Please tell me,

Can these symptoms actually be early signs of lung cancer at my age?
What should I be asking my doctor to check specifically?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

A cough that lasts this long, along with breathlessness, weight loss, and occasional blood in the sputum, definitely deserves proper evaluation, so it is good that your doctor has already started investigating.

At age 35, lung cancer is not common, but it can occur, particularly in people with a past smoking history. That being said, these symptoms are not specific to lung cancer, and several other conditions can cause the same picture. In clinical practice, we often see similar symptoms with infections such as tuberculosis, chronic lung inflammation, bronchiectasis, or sometimes inflammatory lung diseases. Because your X-ray showed an abnormality in the upper lobe, doctors want to look at the lungs in much more detail before making any conclusions.

The symptoms you mentioned

Persistent cough.
Weight loss.
Breathlessness.
Blood in sputum.
Hoarseness of voice.

These are considered warning signs that should always be investigated. They do not automatically mean cancer, but they are reasons to proceed with more detailed imaging and possibly tissue testing if needed.

The PET (positron emission tomography) scan your specialist suggested is usually done to understand whether there is any active abnormal tissue in the lungs or elsewhere in the body. Often, before or alongside that, doctors may recommend a chest CT scan if it has not already been done, because CT imaging provides a much clearer picture of lung structures than a standard X-ray.

From my experience, when someone comes with symptoms like yours, the key steps doctors usually focus on are detailed imaging of the lungs, evaluation of the abnormal area seen on X-ray, and, if necessary, a biopsy to identify the exact cause. These steps help distinguish between infection, inflammation, or a tumor.

I hope this information helps you.
