Scientists test vaccine against prostate, lung and ovarian cancer
Researchers at Oxford Vacmedix, a company created by scientists at the University of Oxford in the UK, are testing a vaccine against prostate, lung and ovarian cancer in volunteers.
The vaccine is designed to attack a protein called survivin, which is released by cancer cells to elude the immune system and prevent the body from attacking them. The immunizer uses a synthetic version of the protein to teach the body to attack the substance and recognize tumors.
The formula is being evaluated in 35 cancer patients in the UK. All will receive three doses, two weeks apart, and will be monitored for six months. Although the immunizer is being tested against all three types of cancer, the expectation is that it will work for everyone.

Extremely common in the country, skin cancer is characterized by the appearance of tumors on the skin in the form of spots or spots with irregular shapes. Related to prolonged exposure to the sun, exposure to artificial tanning cameras or for hereditary reasons, the disease can be treated through surgery, radiotherapy and chemotherapy.miriam-doerr/istock
Breast cancer is caused by the uncontrolled multiplication of cells in the breast. Although common in women, the disease can also affect men. Among the symptoms of the disease are: pain in the breast region, hardened lump, redness, swelling and bloody secretion. Treatment involves surgery to remove the breast, chemotherapy, radiotherapy and hormone therapy.SCIENCE PHOTO LIBRARY/Getty Images
More common in men, prostate cancer has the following symptoms: blood in the urine, difficulty urinating, the need to urinate several times a day and the delay in starting and finishing urinating. Surgery and radiation therapy are among the treatments for the disease.Getty Images
Although it may be related to hyperthyroidism, smoking, changes in sex hormones and diabetes, for example, thyroid cancer is still not well understood by experts. Despite this, treatments against the disease involve hormone therapy, radiotherapy, radioactive iodine and chemotherapy, depending on the case. getty images
Lung cancer is one of the types with the highest incidence in Brazil. Related to the use or prolonged exposure to smoking, its main symptoms are shortness of breath, chest pain, recurrent pneumonia, bronchitis, bloody sputum and frequent coughing. The disease is treated with chemotherapy, radiotherapy or/and surgeryBSIP / getty images
In Brazil, squamous squamous cell carcinoma has the highest incidence among stomach cancers. Treatments involve surgery or radiation and chemotherapyiStock
Stomach cancer is diagnosed after identifying malignant tumors spread throughout the organ that can appear as ulcers. Related to infections caused by Helicobacter Pylori, by the presence of ulcers and untreated chronic gastritis, for example, the disease can cause vomiting with blood or blood in the stool, frequent belly pain and constant heartburnSmith Collection/Gado/Getty Images
Cervical cancer has symptoms of intermittent vaginal bleeding, abdominal pain related to bowel or urinary complaints, and abnormal vaginal discharge. Treatment involves chemotherapy, radiation and surgery.Science Photo Library/GettyImages
Oral cancer is a disease that involves the presence of malignant tumors on the lips, gums, roof of the mouth, tongue, cheeks and bones. It is more common in men over 40 years old and has as symptoms oral cavity sores, tongue stains and neck nodules, for example. Treatment involves surgery, chemotherapy and radiation therapy.pexels
For now, the initial results are promising, but the researchers urge caution: patients need to be followed up to detect long-term side effects and define what the impact is on participants’ survival.
