World Cancer Day is an international day marked on February 4 to raise awareness of cancer and to encourage its prevention, detection, and treatment.

Cochrane Cancer supports and coordinates the work across multiple Cochrane Review Groups dealing with the topic of Cancer. The Network is made up of six Cochrane Review Groups conducting research in Breast Cancer, Childhood Cancer, Gynaecological, Neuro-oncology and Orphan Cancers, Haematology, Lung Cancer and Urology.’  These Cochrane Review Groups provide reliable evidence required to make important decisions on issues concerning cancer and related topics. Cochrane Review Groups facilitate the identification of reports of clinical trials and carry out systematic reviews of available evidence. These are published on the Cochrane Library, and updated periodically as new evidence is identified. This ensures that Cochrane Reviews are relevant, useful, usable, and used.

To mark World Cancer Day, we have collated a selection of  highly viewed Cochrane Reviews on cancer:

• Bortezomib for the treatment of multiple myeloma (Most downloaded Cochrane cancer review)
• Bisphosphonates in multiple myeloma: an updated network meta-analysis (Most talked about/highest altmetirc score)
  
• Lymphadenectomy for the management of endometrial cancer 
• Cannabinoids for nausea and vomiting in adults with cancer receiving chemotherapy
• Prophylactic vaccination against human papillomaviruses to prevent cervical cancer and its precursors
• Intraoperative imaging technology to maximise extent of resection for glioma
• Prophylaxis for Pneumocystis pneumonia (PCP) in non-HIV immunocompromised patients
• Communication skills training for healthcare professionals working with people who have cancer
• Whole brain radiation therapy (WBRT) alone versus WBRT and radiosurgery for the treatment of brain metastases
• Selenium for preventing cancer (Listen to the podcast)
• Obstetric outcomes after conservative treatment for cervical intraepithelial lesions and early invasive disease
• Biopsy versus resection for the management of low-grade gliomas
• Cytology versus HPV testing for cervical cancer screening in the general population
• Anti-angiogenic therapy for high-grade glioma
• Music interventions for improving psychological and physical outcomes in cancer patients
• Exercise interventions on health-related quality of life for cancer survivors
• Yoga for improving health-related quality of life following breast cancer treatment
