Health professionals are encouraging people to be vigilant for two symptoms that manifest at night, as they could be indicators of a potentially fatal disease. Regularly experiencing these unexplained issues could be a sign of cancer. Cancer Research UK has highlighted that both insomnia and severe night sweats can be symptoms of the disease. However, it's crucial to remember that many people suffer from these problems without having cancer - as there are numerous possible causes. But if you observe something unusual for you, such as sudden insomnia or night sweats, it's recommended to seek medical advice. The charity advises: "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." While it's not uncommon to sweat slightly at night due to temperature or sharing a bed with a partner, the charity urges individuals to seek advice if they experience "very heavy, drenching night sweats", or an unexplained fever. Certain cancers, like lymphoma, can cause sweating. It can also be a side effect of medications or infections. Insomnia, characterised by difficulty falling asleep, staying asleep throughout the night, and waking up too early in the morning, is a condition that one in three of us will encounter at some point in our lives, according to the NHS . This sleep disorder can be triggered by a variety of factors including stress, anxiety, illness or injury. Moreover, Cancer Research UK identifies it as a potential symptom of cancer. The charity explains that insomnia could be a consequence of other cancer symptoms such as pain or sickness. However, it could also be a side effect of treatment or induced by worry, anxiety or depression following a diagnosis. Cancer Research UK warns: "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." In addition to insomnia, Cancer Research UK lists other general symptoms of cancer, which include: If you notice any unexplained symptoms, it's crucial to consult your GP.
