COVID-related hair loss is a form of telogen effluvium, a condition in which normal hair shedding ramps up after intense physical or mental trauma. Hair regrowth usually takes six to 12 months. People can speed and support hair regrowth by avoiding harsh hair habits, checking nutrient levels, and applying minoxidil (Rogaine) to the scalp.
Lung cancer kills about 130,000 Americans yearly, but only a tiny percentage of people eligible for low-dose CT lung cancer screening receive it. People qualify for lung cancer screening if they are 50 to 80 years old, have a substantial smoking history as measured in lifetime packs smoked, and currently smoke or quit within the past 15 years. Tens of thousands of lives might be saved each year if everyone who qualified underwent lung cancer screening, which can detect tumors when they are still small enough to be cured with surgery or radiation.

The surgery adds to other weight-loss measures such as diet, exercise, and medications.
