Is vaginal bleeding a symptom of cervical cancer? What is the best food to prevent cervical cancer?

Cervical disease has become the main killer of women, especially middle-aged women. Early cervical cancer often has no obvious symptoms and signs, and the cervix is ​​smooth or difficult to distinguish from cervical columnar epithelial ectasia. Patients with endocervical cancer are easily missed or misdiagnosed because of the normal appearance of the cervix. As the lesion develops, the following manifestations may occur:

1. Symptoms

(1) In the early stage of vaginal bleeding, it is mostly contact bleeding; in the middle and late stages, it is irregular vaginal bleeding. The amount of bleeding varies depending on the size of the lesion and the invasion of the interstitial blood vessels. If it invades large blood vessels, it can cause heavy bleeding. Young patients may also experience prolonged menstruation and increased menstrual volume; elderly patients often experience irregular vaginal bleeding after menopause. Generally, symptoms of exogenous vaginal bleeding occur earlier and the amount of bleeding is larger; this symptom occurs later in endogenous vaginal bleeding.

(2) Most patients with vaginal discharge have vaginal discharge that is white or bloody, can be watery or rice-thin, or have a fishy smell. Late-stage patients may have a large amount of rice-like or purulent leucorrhea due to necrosis of cancerous tissue and infection.

(3) Late-stage symptoms There are different secondary symptoms depending on the extent of cancer involvement, such as frequent urination, urgency, constipation, lower limb swelling and pain, etc. When cancer compresses or involves the ureter, it can cause ureteral obstruction, hydronephrosis and uremia; in the late stage, symptoms of systemic failure such as anemia and malignant diseases may occur.

2. Physical signs

Carcinoma in situ and small invasive carcinomas may not have obvious macroscopic lesions, and the cervix may be smooth or have only columnar epithelial ectasia. Different physical signs may appear as the disease progresses. Exophytic cervical cancer may show polyps and cauliflower pride organisms, often accompanied by infection, and the tumor is fragile and easy to bleed; endophytic cervical cancer is manifested as cervical hypertrophy, hardness, and dilatation of the cervical canal; in the late stage, cancer tissue necroses and falls off, forming ulcers or cavities with a foul odor. When the vaginal wall is involved, the pride organisms on the vaginal wall or the vaginal wall grow; when uterine tissue is involved, double diagnosis and triple diagnosis examinations can touch thickened, nodules, hardness or frozen pelvic cavity.

What should you eat more to prevent cervical cancer?

1. Supplement B-carotene

B-carotene is converted into vitamin A, which helps protect the immune system from attacks by free radical molecules and has a significant immune-enhancing effect. According to scientists, the blood B-carotene level of cervical cancer patients is lower than that of the control group, and the risk factor for cervical cancer is low intake of B-carotene.

Animal foods that contain more vitamin A are: animal liver and eggs. B- Plant foods rich in carotene, such as spinach, rapeseed, amaranth, lettuce leaves, pumpkin, etc.

2. Supplement vitamin C intake

There are more and more examples of cancers caused by viruses. Vitamin C is very important in inhibiting the damage caused by viruses. Recently, scientists have discovered that vitamin C has more than a dozen effects on enhancing immunity, including the production of antibodies and promoting the maturation of immune cells.

In addition, vitamin C is also related to the incidence of cervical cancer. Surveys show that when the intake of vitamin C increases, the risk of cervical cancer decreases. Vitamin C vegetables are mostly green vegetables such as cauliflower, white radish, potato, Chinese cabbage, rapeseed, etc.

3. Supplement trace elements zinc and selenium

Zinc and selenium play an extremely important role in the production and function of immune cells. Scientific research shows that low levels of zinc and selenium in the body can lead to a poor immune system. Cervical cancer is related to trace elements zinc and selenium. Deficiencies in these trace elements lead to a significant increase in the incidence of cervical cancer and breast cancer.

It is particularly important to supplement zinc and selenium in the diet. Animal foods rich in trace elements of zinc and selenium include: oysters, fish, lean meat, animal offal, eggs, beef kidneys, pig kidneys, shrimps, etc., and eggs have the highest zinc content. Plant raw materials containing zinc and selenium include: edible fungi, seaweed, sesame, peanuts, wheat germ powder, nuts, etc.

4. Eat more soybeans and their products

Such as tofu, soy milk, dried tofu, celery, broccoli, edamame, sweet peas and other vegetables. Since these foods can supplement phytoestrogens, the isoflavones and lignin contained in phytoestrogens are considered by scientists to have antioxidant effects. Phytoestrogens can inhibit the growth of cervical adenocarcinoma and squamous cell carcinoma, inhibit cell division, and effectively prevent the invasion or metastasis of cancer cells.
