Does vulvar cancer spread quickly if not treated with chemotherapy?
Vulvar cancer is a type of malignant tumor in women. For patients in the early stages of vulvar cancer, chemotherapy is generally not required after radical surgery. Even without chemotherapy, the disease progression of early-stage vulvar cancer is relatively slow, and many patients can achieve clinical cure after the radical surgery. However, for patients with mid-to-late stage vulvar cancer, postoperative adjuvant chemotherapy is generally required after the radical surgery to reduce the chances of disease recurrence and metastasis. Without postoperative adjuvant chemotherapy, the disease can spread quickly, and many patients soon experience the spread of the disease, eventually leading to multi-organ failure and death. Therefore, it is essential for patients who need adjuvant chemotherapy to complete the supplementary treatment regularly and on time after surgery.
What tests are needed to determine the cause of vulvar cancer?
Vulvar cancer is a type of malignant tumor in female gynecology. Clinically, the following examinations can be used to identify the cause of vulvar cancer. First, testing for human papillomavirus (HPV) can be conducted. If the patient is found to be infected with HPV, then the cause of vulvar cancer can be considered to be due to viral infection. Additionally, herpes virus testing can also be performed, as many patients with vulvar cancer are caused by herpes virus infection. Thirdly, cytological examination of the vulva can be conducted to detect if there are any malnutritive lesions, such as vulvar lichen sclerosus, and other diseases like dermatophytosis, which are also reasons for the high incidence of vulvar cancer.
Early symptoms of tongue cancer
The early symptoms of tongue cancer patients are mainly manifested as ulcerous lesions on the surface of the tongue, which relapse frequently. The effectiveness of common anti-inflammatory drugs and ulcer treatments is poor. The edges of these ulcerative lesions are rough and the bottom is unclean, often accompanied by abnormal secretions. When infected, the area may exhibit bleeding, pain, and other symptoms. Additionally, some early-stage patients may develop nodular lesions on the surface of the tongue. These nodules have irregular edges and tend to adhere to the surrounding tongue tissues. They are relatively hard, and their surfaces are prone to friction, bleeding, and even exhibit signs of inflammation such as redness and swelling.
Does vulvar cancer ulceration infect family members?
Vulvar cancer is a malignant tumor of the female reproductive system with a low incidence rate clinically. Many patients with vulvar cancer experience ulcerations in their lesions. Even when ulceration occurs in vulvar cancer lesions, it is not contagious to family members because vulvar cancer is a malignant tumor and does not possess contagiousness. The occurrence of infectious diseases necessarily requires three core elements: a source of infection, a transmission route, and a susceptible population. The formation of an infection without these three elements is impossible. When ulceration occurs in vulvar cancer lesions, it is due to the tumor lesion and is non-contagious; however, it is prone to concurrent infections, causing clinical symptoms such as fever, localized pain, and bleeding, which greatly afflict the patients. In cases of ulceration in vulvar cancer, besides controlling the infection and managing local symptoms, it is also necessary to provide aggressive anti-tumor treatment.
Will the vulvar cancer be rotten in the late stage?
Patients with advanced vulvar cancer do not all show signs of internal ulceration. This is because, for most patients with vulvar cancer, the progression of the disease can lead to invasion of the surrounding tissues or distant metastasis. Some patients may experience heavy local infiltration, leading to tissue ulceration. However, most patients in the advanced stages primarily show symptoms related to lymphatic and hematogenous metastasis. When patients with advanced vulvar cancer develop lymph node metastasis and distant metastasis, they may experience symptoms of metastatic lesions, such as inguinal lymph node metastasis causing limb swelling and pain. If there are distant metastases to the lungs, liver, or other areas, patients may exhibit respiratory symptoms such as coughing and expectoration, or liver-related symptoms such as pain in the liver area or decreased appetite.
Can vulvar cancer be detected through an HPV test?
Vulvar cancer cannot be detected through an HPV test, as the HPV test is a virological examination specifically designed to determine the presence of the human papillomavirus infection, but it cannot confirm the existence of vulvar cancer. Clinically, examinations for vulvar cancer primarily include a detailed physical examination to ascertain the presence of lumps, ulcers, or lesions on the vulva. Additionally, vulvar ultrasound, CT, or MRI can be performed to understand the extent of vulvar cancer invasion. A pathological examination of vulvar cancer can also be conducted to diagnose the disease.
What will happen when vulvar cancer becomes severe?
Vulvar cancer is a malignant tumor of the female reproductive system. When vulvar cancer becomes severe, the lesions metastasize to many areas, which can cause serious clinical symptoms, severely affect the patient's quality of life, and even endanger the patient's life. For example, if vulvar cancer metastasizes to the inguinal lymph nodes, pain can occur in the area of the metastases. Additionally, mobility of the limb on the side of the metastases is limited, and swelling of the lower limb occurs. If the patient's lesions metastasize to the lungs through the hematogenous route, clinically the patient may experience coughing, expectoration, chest tightness, chest pain, and even some patients may have respiratory failure, which severely threatens their life. Some patients have bone metastases, and besides pain in the area of the bone metastases, some patients also experience pathological fractures, limited mobility, and significant pain.
Is conservative treatment or surgery better for vulvar cancer?
Vulvar cancer is a malignant tumor in female gynecology. There are various treatment options for patients with vulvar cancer. The choice between surgical treatment and conservative treatment depends on multiple factors such as the patient's clinical stage and physical condition. For patients with early-stage vulvar cancer, radical surgical excision is the best treatment method. However, some patients with poor physical condition may not tolerate surgery and may instead receive curative radiotherapy or systemic chemotherapy as an alternative treatment. For patients with mid-to-late stage vulvar cancer, the best treatment method is comprehensive internal medicine treatments, such as chemotherapy and targeted therapy. For patients with advanced vulvar cancer who have a poor physical condition and cannot tolerate chemotherapy or other antitumor treatments, the best treatment method is conservative treatment aimed at maintaining stable vital signs.
Is vulvar cancer stage III considered advanced?
Vulvar cancer is a type of malignant tumor in women's gynecology, which has a relatively low clinical incidence rate. For stage III vulvar cancer, it is considered advanced vulvar cancer. Advanced vulvar cancer indicates that the lesion has spread. For vulvar cancer with lesion spread, surgical treatment should be pursued if possible. For patients who cannot undergo surgery, options like chemotherapy, radiotherapy, targeted therapy, and other comprehensive combined treatment methods can be considered for cancer treatment. However, for patients with advanced vulvar cancer, the aim of treatment is mainly to improve the quality of life and extend the survival time, as complete clinical cure of the tumor is not possible. Only early-stage vulvar cancer, after receiving curative surgery or curative radiotherapy, may achieve a clinically cured effect.
Is the vulvar cancer nodule soft or hard?
Vulvar cancer clinically forms nodular lesions that are generally hard in texture with poor mobility and tend to adhere to surrounding tissues, and have indistinct borders. Due to the rapid growth of the nodules, their shape is usually irregular, easily forming granulomatous or cauliflower-like appearances, and they are prone to contact bleeding. Patients with vulvar cancer typically have nodular lesions that are likely to invade surrounding tissues or metastasize to lymph nodes. The chances of distant metastasis to the lungs, liver, bones, or brain are relatively lower. Clinically, it is common to see enlarged inguinal lymph nodes and pain caused by metastatic foci. Some patients may also experience local skin metastasis, subcutaneous nodules, or skin itching as clinical manifestations. For the treatment of vulvar cancer, radical surgery is primarily recommended, with radiation therapy and chemotherapy also being effective options.
