Congestion
This is also known as a stuffy nose. It is characterized by a runny or stuffy nose, mucus build up, sinus pain and swollen nasal tissue. If congestion is caused by a common cold, home remedies should be enough to treat it. However, if congestion goes on long term, it is one of the symptoms of throat cancer. In this case, medical treatments may be required if the condition gets too painful and it begins to interfere with your daily activities.
There is a possibility to take the signs and symptoms of throat cancer for other health conditions. It is therefore important to see a doctor when you begin to experience these symptoms persistently.
Conclusion
An individual should visit a doctor if any of these throat cancer symptoms is experienced for over 3 weeks. [8] A doctor would conduct the right tests to establish the cause of the symptoms and to know whether they are because of throat cancer or something else.
