New cervical cancer treatment reduces death risk by 40%
Understanding Cervical Cancer: Causes, Symptoms, and Prevention
- Cervical cancer is a type of cancer that occurs in the cells of the cervix, the lower part of the uterus that connects to the vagina. It is one of the most common cancers affecting women globally, but it is also one of the most preventable forms of cancer when detected early. Significant advancements in screening and vaccination have made it possible to reduce the incidence and mortality rates associated with the disease.
Causes of Cervical Cancer
- The primary cause of cervical cancer is persistent infection with high-risk types of human papillomavirus (HPV). HPV is a common sexually transmitted infection, and while most HPV infections clear up on their own, some can persist and lead to cancerous changes in cervical cells over time. There are over 100 types of HPV, but only a few, such as HPV-16 and HPV-18, are responsible for most cervical cancers.
Other risk factors include:
1- Weakened immune system: Individuals with weakened immunity, such as those with HIV, are at a higher risk.
2- Smoking: Tobacco use has been linked to an increased risk of cervical cancer.
3- Multiple sexual partners: Having multiple sexual partners increases the risk of HPV infection.
4- Long-term use of birth control pills: Prolonged use of oral contraceptives has been linked to a slightly increased risk of cervical cancer.

Symptoms of Cervical Cancer
- Cervical cancer in its early stages often does not cause noticeable symptoms. This is why regular screening is crucial for early detection. As the cancer progresses, the following symptoms may develop:
1- Abnormal vaginal bleeding: This may occur between periods, after intercourse, or after menopause.
2- Unusual vaginal discharge: Discharge may be watery, bloody, or have a foul odor.
3- Pelvic pain: Persistent pain in the pelvic region may occur, especially during intercourse.
If you experience any of these symptoms, it is important to seek medical advice as soon as possible.

Diagnosis and Screening
- Cervical cancer is often detected through routine screening. The two most common methods for early detection are:
1- Pap smear (Pap test): A Pap smear collects cells from the cervix to detect any abnormal changes that may indicate precancerous or cancerous cells.
2- HPV testing: HPV tests can identify the presence of high-risk HPV strains that may lead to cervical cancer.
- In many countries, women aged 21 to 65 are encouraged to undergo regular Pap smears and/or HPV testing to catch the disease in its early stages. Early detection through screening can prevent the development of cervical cancer or catch it when it is most treatable.

Treatment Options
- Treatment for cervical cancer depends on the stage at which it is diagnosed. Common treatment methods include:
1- Surgery: In early-stage cervical cancer, surgery to remove the tumor may be performed. This can include a hysterectomy (removal of the uterus), which may be necessary to prevent the cancer from spreading.
2- Radiation therapy: Radiation is often used in combination with chemotherapy for more advanced cases. It works by targeting and destroying cancer cells.
3- Chemotherapy: Chemotherapy uses drugs to kill cancer cells and is usually used in cases where the cancer has spread beyond the cervix.
4- Targeted therapy: Targeted therapies attack specific cancer cells without harming normal cells. Immunotherapy is another option that helps the body’s immune system fight cancer.
- Recent advancements in treatment, including new drug regimes, have significantly improved survival rates. Studies have shown that modern treatments can reduce the risk of dying from cervical cancer by as much as 40%.

Prevention
- Prevention is key in the fight against cervical cancer. The following measures can reduce the risk:
1- HPV Vaccination: Vaccines like Gardasil and Cervarix protect against the most dangerous strains of HPV. The vaccine is recommended for girls and boys, usually between the ages of 9 and 12, but it can be given up to age 26.
2- Regular Screening: Regular Pap smears and HPV tests are crucial for early detection.
3- Safe sexual practices: Using condoms and limiting the number of sexual partners can reduce the risk of HPV infection.
4- Quitting smoking: Reducing tobacco use can lower the risk of developing cervical cancer.
- Cervical cancer remains a serious health concern, but with early detection, proper vaccination, and effective treatments, it is largely preventable and manageable. Women should prioritize regular screenings and HPV vaccination to reduce their risk, and seek medical attention if they notice any concerning symptoms. As awareness and access to preventive measures increase, the global burden of cervical cancer continues to decrease.

New Cervical Cancer Treatment Reduces Death Risk by 40% in Major Breakthrough
- Doctors are celebrating a significant advancement in cervical cancer treatment, with a new regimen that reduces the risk of death by 40%. This marks the most important progress against the disease in 25 years.
- Cervical cancer is the fourth most common cancer in women worldwide, with the World Health Organization reporting around 660,000 new cases and 350,000 deaths each year. In the UK alone, approximately 3,200 women are diagnosed annually, and about 800 die from the disease. Many women affected are in their 30s, and despite improvements in care, the cancer returns in about 30% of cases.
- The new treatment approach was developed through a 10-year study involving patients from the UK, Mexico, India, Italy, and Brazil. It includes a short course of chemotherapy followed by chemoradiation, the standard treatment combining chemotherapy and radiotherapy. This new approach has been shown to significantly increase survival rates.
- In a phase-three clinical trial led by University College London (UCL), the new treatment reduced the risk of death by 40% and the chance of cancer recurrence by 35% over at least five years. These findings, published in The Lancet, represent a major milestone in cervical cancer research.
- Dr. Mary McCormack, the lead researcher, called this the most significant breakthrough in treating cervical cancer since chemoradiation was introduced in 1999. She emphasized that every improvement in survival is crucial, especially when the treatment is well-tolerated and allows patients to return to their normal lives quickly.
- The study, known as the Interlace trial, involved 500 women who were randomly assigned either the new treatment or standard chemoradiation. The new regimen included six weeks of chemotherapy (carboplatin and paclitaxel), followed by standard radiotherapy and weekly chemotherapy (cisplatin) along with brachytherapy. After five years, 80% of the women who received the new treatment were alive, and for 72% of them, the cancer had not returned or spread. In contrast, in the group that received only the standard treatment, 72% survived, and 64% had not experienced a recurrence.
- The results highlight the remarkable effectiveness of adding a short course of chemotherapy before standard treatment. McCormack stated that this approach could easily be implemented worldwide using already approved and affordable drugs. Some cancer centers have already adopted the new regime, and there are calls for it to be made available to all patients undergoing chemoradiation for cervical cancer.
- One patient, Abbie Halls, was diagnosed with cervical cancer at 27 and participated in the trial. She has been cancer-free for over nine years and credits the new treatment with saving her life. “I’m happy that I could help advance the research, and I hope it will save the lives of many more women,” she said.

He noted that adding chemotherapy before other treatments like surgery or radiotherapy is increasingly shown to improve outcomes, reducing the likelihood of cancer returning and providing hope for patients worldwide.
