2026 World Lung Cancer Day

It’s World Lung Cancer Day 2026! And yet, even in 2026, lung cancer still carries an unfair stigma and burdens patients with guilt. Too many patients feel they must explain themselves before they are allowed to receive compassion. But nobody deserves lung cancer, and every person facing it deserves excellent care, scientific progress, and hope.

Fortunately, today there is more reason for hope than ever before.

Over the past two years, lung cancer treatment has continued to change at a remarkable pace. Immunotherapy, once used mainly for advanced disease, is now being given before surgery, after surgery, and following chemotherapy and radiation. For some patients, these treatments reduce the chance that the cancer will return.

Precision oncology has transformed the way we think about lung cancer. We no longer see it as a single disease. We now test tumors for molecular changes involving genes such as EGFR, ALK, ROS1, KRAS, RET, MET, BRAF, and HER2. These results guide treatments designed for the specific biology of an individual cancer. For patients diagnosed with stage II or later-stage disease, comprehensive molecular testing is an essential and standard part of excellent lung cancer care.

Liquid biopsy is becoming increasingly useful as well. By studying fragments of tumor DNA found in the bloodstream, we can identify important mutations that may guide therapy. These blood tests can also help us understand why a treatment has stopped working, potentially allowing the oncologist to switch to a more effective therapy. They do not replace tissue biopsy in every situation, but they are becoming an important companion to it.

Small-cell lung cancer, which saw frustratingly little progress for many years, has also gained new treatment options. Immunotherapy is moving into earlier stages, and new therapies directed against targets such as DLL3 are creating possibilities where few existed before.

Screening remains one of our strongest tools. Annual low-dose CT scans can find lung cancer before symptoms develop, when it is more likely to be curable. The challenge is making sure that people at risk know screening exists, can access it, and return year after year.

Smoking cessation remains equally important, but it must be offered without judgment. Counseling, medication, and continued support work better than a lecture. Quitting still matters, even after a lung cancer diagnosis, and can improve treatment outcomes and overall health.

Too often, lung cancer remains a hidden diagnosis, suffered in silence and without the funding necessary to support the research that finds the next treatment. This is why I wear the kilt. The kilt is visible. It gives me an opening to talk about screening, research, clinical studies, and the people whose lives depend on these advances reaching the clinic.

On World Lung Cancer Day, we honor those living with lung cancer, remember those we have lost, and continue the work of finding it earlier, treating it better, and refusing to let stigma have the final word.

Research cures. Screening saves lives. And sometimes, a kilt starts the conversation.
