DEVELOPING CAPACITY OF PRIMARY HEALTH CENTRES IN SCREENING, EARLY DIAGNOSIS AND APPROPRIATE REFERRAL OF CERVICAL CANCER IN A LOW-RESOURCE SETTING: A PILOT INTERVENTIONAL STUDY

Shehu Salihu Umar*, Aisha Jamila Ahmad, Anisa Yahya, Mus’ab M. Dalhat, Kabiru Adamu, Khadija M. Kanoma, Zaharaddeen Shuaibu Babandi, Muazu Abdus-Salam, Benjamin O. Popoola

Background: Despite cervical cancer being preventable and treatable if detected early, it is predominantly characterised by late presentation with advanced disease in low-resource settings. This is due to a poor level of awareness of cervical cancer in the population. The Primary Health Centres (PHCs), which constitute 85.4% of all registered health facilities in Nigeria, serve as the first level ...

Oiza Tessy Ahmadu*, Shehu Salihu Umar, Saad A Ahmed, Aminu Liman, Trevor Mdaka

Introduction: The presence of metastasis is the most important factor affecting overall survival of patients with breast cancer. Though tremendous progress has been made in area of treatment, 20-30% of patients will develop metastasis, with the skeleton as one of the major sites of distant spread. There is marked variability among breast cancer patients who develop metastasis including the pattern...

ASSESSMENT OF DELAYS AMONGST CERVICAL CANCER PATIENTS IN A RADIOTHERAPY FACILITY: A PROSPECTIVE STUDY

Shehu Salihu Umar*, Adamu Abdullahi, Aisha Jamila Ahmad, Oiza Tessy Ahmadu, Anisa Yahya

Introduction: Globally, cervical cancer is the 8th commonest malignancy and the fourth commonest in females. However, in Sub-Saharan Africa, the incidence and mortality from cervical cancer is second only to breast cancer, and actually highest in some of the countries. Most cases of cervical cancer in Sub-Saharan Africa are diagnosed at advanced stages, largely due to the various delays. These inc...
