Some lung cancers realise hormone-like essences that affect blood calcium degrees, feigning guts and muscles and justification weakness and dizziness.
How Are Signs and Symptoms Helpful?

It is easily removed if it has not yet grown deep into the skin, and the 5-year survival rate( percentage of people living at least 5 years after diagnosis) at this stage is nearly 100%. But formerly melanoma has spread to other areas of the body the survival rate fells dramatically.
Sometimes people neglect symptoms either because they do not recognize the symptoms as being substantial or because they are frightened by what they might aim and don’t want to seek medical assistance.
