Persistent fatigue
“Cancer-related fatigue is often described as an overwhelming exhaustion that does not improve with sleep. There are many possible explanations, including anemia, thyroid disorders, infections and poor sleep, but persistent fatigue should always be discussed with your doctor if there is no improvement.”
Persistent cough
“ Persistent cough does not automatically mean cancer In fact, there are many other more common causes. However, as most coughs associated with colds and viral infections disappear in a few weeks, a cough that does not disappear or worsen gradually after this period justifies consultation with a doctor.”
Unexplained weight loss
“ If you are losing weight despite eating normally and have not intentionally changed your lifestyle, it is important to understand why. Often there will be another explanation, but it is not something that should simply be ignored.”
