Why is there blood in saliva? Cancer

Some friends found blood in their saliva. There are many reasons for this situation, but if there is blood in the saliva for a long time, some people will think they have cancer. In fact, if there are cancer cells in our body, the body will show many symptoms. So, why does the presence of blood in saliva really mean that you have cancer?

Common causes of blood in the mouth include:

One is oral diseases: such as oral ulcers, gingivitis, periodontitis, and dental tartar.

Oral ulcer is one of the most common oral mucosal diseases. It is a localized ulcer lesion of the oral mucosa characterized by periodic recurrence. It can heal itself and can occur in any part of the oral mucosa, more commonly on the lips, cheeks, and tongue. In severe cases, it can affect the pharyngeal mucosa.

The accumulation of periodontal calculus, coupled with the influence of dental plaque on it, can cause gingivitis. In the later stages, the alveolar bone is absorbed and periodontal pockets are formed, which will develop into periodontal disease. Gingival inflammation will manifest as red and swollen gums, loose texture, and easy bleeding, often manifested as blood in sputum in the morning and blood in the mouth when brushing teeth. In addition, if the impacted tooth can be diagnosed, if it has no normal function, it is easy to cause repeated lesions of the surrounding soft tissues and adjacent teeth. If the patient's physical condition permits, extraction can be considered.

The second is digestive tract diseases: such as diseases of the esophagus and stomach, but generally there are diseases such as gastric ulcers, and they all occur during vomiting.

The third is respiratory system disease, which occurs when you spit out saliva when you cough.

It is recommended that you feel which part is more likely to be affected according to your own situation, and then go to the hospital for a comprehensive examination of the corresponding part. This way you can confirm what the disease is, but the possibility of cancer is very small!
