There is no such thing as where Bowen’s disease grows is the most dangerous, Bowen’s disease is not a serious disease, so no matter where it grows, the danger is usually not high, but it should be consulted and treated in a timely manner, because if Bowen’s disease continues to grow and is not treated in a timely manner, it may deteriorate further into invasive squamous cell carcinoma, which has a poor prognosis. Bowen’s disease is a kind of in situ squamous cell carcinoma of the skin, which is usually confined to the epidermis of the patient, and will not invade to the deeper layers, therefore, it is a kind of very early malignant tumor of the skin, which is most common in the trunk and limbs, and it is not dangerous because it is not very life-threatening to the patients, and it can be cured usually. However, the diagnosis should not be delayed and the disease should be treated as soon as possible. However, if Bowen’s disease continues to grow and is not treated in time, it may further deteriorate into invasive squamous cell carcinoma, which has a poor prognosis. If the skin surface is exposed to sunlight for a long time and the organism has chronic arsenic poisoning, it is prone to Bowen’s disease. The patient’s skin surface is prone to the appearance of well-defined reddish-brown plaques, and there may also be a small amount of scales on the plaques. If diagnosed with Bowen’s disease, it can be treated with surgical excision and cryotherapy as prescribed by the doctor. Since the lesions are only confined to the epidermis, the condition is easier to cure. It is important to seek medical attention and treatment as soon as possible.
