Health experts are urging people to look out for two symptoms that appear at night as they could be warning signs of a potentially deadly disease. If you regularly experience these unexplained issues they could signal cancer.
According to Cancer Research UK, both insomnia and heavy night sweats can be a symptom of the disease.
However, it is important to note that many people suffer from these problems and don’t have cancer – as they have many possible causes.
But if you notice something that is not usual for you, such as sudden insomnia or night sweats, you should seek medical help.
The charity says: “It’s important to be aware of what is normal for you and speak to your doctor if you notice any unusual changes or something that won’t go away. This can help to diagnose cancer at an early stage, when treatment is more likely to be successful.”
Insomnia
Insomnia, or difficulty sleeping, is when you have difficulty falling asleep and staying asleep at night, and waking up too early in the morning.
The NHS says that one in three of us will experience problems with sleeping at least once in our lives.
This can be due to a myriad of reasons such as stress, anxiety, illness or injury. And Cancer Research UK lists it as a potential symptom of cancer.
The insomnia could be a result of other symptoms of the cancer such as pain or sickness, the charity explains.
But it can also be one of the side effects of treatment or brought on by worry, anxiety or depression following a diagnosis.
Cancer Research UK says: “If you often have insomnia, it can interfere with everyday life. You may feel very tired, and have low energy. You might also have poor concentration, and irritability, and may feel you cannot cope.”
Heavy night sweats
It’s not uncommon to sweat a bit at night. This could be due to the temperature or sleeping next to a partner.
However, the charity urges people to seek advice if they have “very heavy, drenching night sweats”, or an unexplained fever.
Certain cancers such as lymphoma can themselves cause sweating.
It can also be a side effect of medications or infections.
Other general symptoms of cancer as listed by Cancer Research UK, include:
- Fatigue
- Unexplained bleeding or bruising
- Unexplained pain or ache
- Unexplained weight loss
- Unusual lump or swelling anywhere.
If you experience any unexplained symptoms you should speak to your GP.
