My dad (72 yrs old) is currently under investigation for lung cancer. Hes had a few CT scans now which have indicated a growth and features consistent with lung cancer. He's recently had a PET scan, and a lung biopsy (approx 1 week ago) so just waiting for the formal results now.

We have noticed over the past couple of weeks, he is sweating excessively. Hes usually quite an active person but even the slight little bit of movement (very short walk from the house to the car say) will cause him to sweat excessively +++ - to the point hes then needing to jump into the shower. They aren't night sweats but occur more in the day, and he describes it as being a cold sweat.

He does have a GP appointment to discuss this, but can this be linked to possible cancer at all, and is there any way to manage it? (It's getting him abit down). He is otherwise well, no signs of illness, no other symptoms really, no fever

Thanks
