Lung Cancer: Unusual Signs You Need to Know
22 Feb
Summary
- Lung cancer was the most common cancer globally in 2022.
- Smoking causes about 85% of all lung cancer cases.
- Unusual signs like finger clubbing and shoulder pain can indicate lung cancer.
Lung cancer remained the most prevalent cancer globally in 2022, with 2.5 million new diagnoses and responsible for 1.8 million fatalities. Smoking is identified as the primary cause, contributing to approximately 85% of all lung cancer instances. The disease is frequently diagnosed at advanced stages, limiting treatment options, often because early indicators are overlooked.
Several unusual symptoms can signal lung cancer, distinct from typical respiratory issues. These include finger clubbing, where fingertips widen and nails curve; persistent shoulder or arm pain, potentially indicating a Pancoast tumor; and unexplained hoarseness due to tumors pressing on vocal cord nerves.
Other subtle signs involve swelling in the upper body, such as facial puffiness or arm swelling, caused by the obstruction of the superior vena cava. Horner syndrome, characterized by a drooping eyelid, constricted pupil, and reduced sweating on one side of the face, can also be an indicator. Additionally, excessive thirst and frequent urination may signify lung cancer through paraneoplastic syndromes.
Early detection of these varied signs is critical for improving treatment outcomes. Individuals experiencing these symptoms should seek prompt medical evaluation to facilitate timely diagnosis and intervention.
