When a patient has liver cancer, one symptom can be gingival bleeding. Because when a patient has liver cancer, some coagulation factors in the blood are affected, and the patient may frequently experience repeated dental bleeding. Therefore, it is suggested that patients should undergo early diagnostic tests and adopt specific treatment plans. However, repeated gingival bleeding in a patient does not necessarily indicate early-stage liver cancer, as some hematological diseases can also lead to repeated gingival bleeding, such as common thrombocytopenia and some patients with gingivitis. If long-term oral hygiene is neglected, the gingival tissue stays in a state of chronic inflammation, and acute inflammation can lead to bleeding while brushing teeth.
