Uterine cancer etiology is unclear, some people think about the risk factors of cervical squamous cell carcinoma have similar characteristics, such as early sexual intercourse, sexual disorders, multiple sexual partners, but also with similar characteristics of endometrial cancer, infertility, pregnancy less who, obesity, hypertension and diabetes significantly higher rate of cervical squamous cell carcinoma. Some scholars believe that the risk factors of cervical adenocarcinoma and squamous cell carcinoma of the cervix is different childbirth without much thought life and relationship with adenocarcinoma, and may be associated with endocrine disorders and administration of exogenous sex hormones.
Uterine cancer mostly occurs during menopause, and this period is often disturbed hormone related. In the application of progesterone drugs and pregnant women, the cervix can be seen in the micro-glandular hyperplasia (microg-landular hyperplasis), which is due to progesterone stimulation of cell proliferation under reserve endocervical columnar cells to glandular differentiation, Description gland hyperplasia and progesterone related. Qizilbash, Gallup and so that if high doses of progesterone preparations serving for more than 10 years or 10 years, increased risk of cervical cancer. Gallup reported 35 cases of cervical adenocarcinoma in 28 cases had received sex hormone preparations, including three cases had used estrogen and progestin combination therapy. Some scholars have also noted that the relationship between cervical cancer and the long-term use of contraceptives among. Ireland reported 73 cases of cervical cancer patients in eight cases had been taking birth control pills, Gallup reported 35 cases of cervical cancer patients in five cases had been taking the pill 1 to 8 years. Most of the material due to small number of cases, it is a causal relationship between the pill and cervical cancer is hard conclusive, but it is worth attention.
Biological studies have shown that the occurrence of cervical cancer and human papillomavirus (HPV) infection is closely related. In cervical squamous cell carcinoma and adenocarcinoma can be detected HPV DNA, HPV and cervical cancer associated with 16, 18 and 31-based, but in cervical squamous cell carcinoma and adenocarcinoma is not the same as the proportion of HPV type. HPV16 in cervical squamous cell carcinoma in the main, 5% ~ 17% HPV18 only HPV-positive tumors, and HPV18 in cervical adenocarcinoma in the main proportion of up to 34% ~ 50%, suggesting that HPV 16,18 particularly is HPV18 may play an important role in the pathogenesis of cervical cancer.
So, the incidence of uterine cancer have some symptoms characteristic of it? Experts say the incidence of uterine cancer are five common symptoms.
Large inventory of uterine cancer symptoms
1, systemic symptoms
Patients with advanced cancer tissue due to metabolism, absorption or merger of necrotic tissue infection causes fever, body temperature usually around 38 degrees, a few up to more than 39 degrees. Because of bleeding, consumption anemia, weight loss and even cachexia.
2, increased secretions
Vaginal bleeding occurred in the past, one of the main symptoms of these diseases people. Initially vaginal secretions may not have any odor, along with the growth of cancer, carcinoma secondary infection, necrosis, increase the amount of the secretions, such as rice water samples or mixed blood, and with a bad smell. Involving the upward spread of tumor endometrial, patients may present abdominal discomfort, abdominal pain, back pain and fever and other symptoms.
3, other symptoms
Proliferation of cancer can be violated forward to the bladder, the patient urinary frequency, urgency, dysuria, hematuria fall and is often misdiagnosed as a urinary tract infection and delay in diagnosis.
4. Pain
Is a symptom of advanced cervical cancer. Cancer tissue extends along the side violated the pelvic wall, nerves, clinical manifestations of oppression around the sciatic nerve or persistent pain on one side of the sacral iliac portion. Ureteral tumor compression or erosion, piping stenosis, obstructive cause hydronephrosis, showing a side back pain, even pain, further development of renal failure, resulting in uremia. Lymphatic system involvement leads to lymphatic obstruction, flow obstruction and lower extremity edema and pain and other symptoms.
5, vaginal bleeding
Irregular vaginal bleeding is the main symptom of cervical cancer patients. Accounting for about 80%, especially in post-menopausal vaginal bleeding should attract attention. Vaginal bleeding can be more or less, vaginal bleeding is often caused by tumor blood vessels rupture, especially vegetables tumor bleeding symptoms appear earlier than the amount from the blood loss can lead to severe anemia. Advanced cases, there may be a lot of vaginal bleeding that shock, common in the aggressive growth of the tumor.

Garlic
Garlic, known as "ground grow penicillin," said that it is rich in allicin and selenium and other trace elements, regular consumption, for the prevention of cancer progression, and improve the body immunity are very helpful.
Cauliflower
It is reported that British researchers found that two-indole methane can help prevent women suffering from uterine cancer. This is the latest study by the Medical University of Wales researchers have demonstrated. And this chemical products, such as broccoli and cabbage vegetables abound.
Tomato
Tomatoes, rich in antioxidants and lycopene, can effectively remove free radicals, play cancer, tumor suppressor role. Regular consumption of tomatoes, in particular, to reduce the risk of lung cancer, stomach cancer, bladder cancer, uterine cancer, skin cancer, prostate cancer risk.
Pumpkin and carrots
Pumpkins and carrots, rich in carotenoids can play a role in anti-oxidants, by removing free radicals, prevent lung cancer. Carotene in the body can be transformed into essential human nutrient elements vitamin A, can prevent normal cells cancerous.
Pineapple
Pineapple, rich in proteases, can relieve sore throat and cough, arthritis and gout, accelerate protein digestion. The latest study also showed that consumption of pineapple for the prevention and treatment of cancer is also very effective.
