Yes, lung cancer misdiagnoses are possible. According to the Moffitt Cancer Center, lung cancer can be misdiagnosed as pneumonia, asthma, or other types of cancer like lymphoma.
Thus, it’s a good idea to always get a second opinion to ensure you were properly diagnosed if lung cancer is suspected. If lung cancer is misdiagnosed, doctors won’t be able to treat it properly and you could have less time to live.
