Cancer In Bolivia: Understanding The Most Common Types

Bolivia has one of the highest cervical cancer mortality rates in the Americas. Cervical cancer is the most common cancer among women in Bolivia, with the highest age-standardized incidence rates of cervix uteri in females (36.6/100,000 females). In 2022, it was the most common cancer among newly diagnosed people in Bolivia, with around 2,200 patients. Bolivia also has the highest incidence rates of gallbladder cancer worldwide. The most common cancers in Latin America and the Caribbean, where Bolivia is located, are breast, prostate, and colorectal cancer.

Cervical cancer is the most common cancer among women in Bolivia

Cervical cancer is a type of cancer that starts in the cells of the cervix, which is the lower, narrow end of the uterus (womb). The cervix connects the uterus to the vagina, also known as the birth canal. Most cervical cancers begin in the area where the endocervix and ectocervix meet, called the squamocolumnar junction or transformation zone.

The high incidence of cervical cancer in Bolivia reflects the major inequities driven by a lack of access to national HPV vaccination, cervical screening, and treatment services. HPV, or human papillomavirus, is a common sexually transmitted infection that can affect the genital area. Persistent infection with high-risk HPV can cause abnormal cells to develop, which can eventually turn into cancer.

To address this health issue, countries around the world have set three targets to be met by 2030:

• 90% of girls vaccinated with the HPV vaccine by age 15
• 70% of women screened with a high-quality test by ages 35 and 45
• 90% of women with cervical disease receiving treatment

By achieving these targets, it is estimated that a cumulative 74 million new cases of cervical cancer can be averted, and 62 million deaths can be avoided by 2120.

Bolivia has one of the highest cervical cancer mortality rates in the Americas

Cervical cancer is the fourth most common cancer among women globally. In 2022, there were more than 662,301 new cases of cervical cancer worldwide, with Eswatini and Zambia having the highest rates. In Bolivia, cervical cancer is the most common type of cancer among newly diagnosed patients. In 2022, around 2,200 new cases of cervical cancer were reported in the country, surpassing other common cancers such as prostate and breast cancer.

Several factors may contribute to Bolivia's high cervical cancer mortality rate. One reason could be limited access to healthcare services and screening programs. Additionally, socioeconomic factors, such as poverty and lack of education, can play a role in the high mortality rate. Cultural barriers and stigma associated with cervical cancer may also hinder women from seeking timely medical attention. Furthermore, the country's geographic diversity and dispersed population can make it challenging to provide uniform healthcare services, including cancer prevention, detection, and treatment.

To address the high cervical cancer mortality rate in Bolivia, a comprehensive approach is necessary. This includes improving access to healthcare services, particularly in rural and underserved areas, through the development of adequate infrastructure and the expansion of health insurance coverage. Additionally, increasing awareness about cervical cancer prevention, screening, and treatment options is crucial. Educational campaigns can play a vital role in empowering women to seek medical attention promptly and reducing any associated stigma.

Furthermore, ensuring the availability of HPV vaccines, which can prevent cervical cancer, is essential. Early detection through regular Pap smear tests and HPV screening can significantly improve survival rates. Strengthening the healthcare system's capacity to provide timely and effective treatment, including surgery, radiation therapy, and chemotherapy, is also vital. By addressing these issues, Bolivia can make significant strides in reducing its cervical cancer mortality rate and improving the overall health and well-being of its female population.

Bolivia and Chile have the highest gallbladder cancer rates in the world

Bolivia and Chile have the highest rates of gallbladder cancer in the world. In 2022, the most common type of cancer in Bolivia was cervix uteri cancer, with around 2,200 patients diagnosed. This was followed by prostate cancer (1,935 new cases) and breast cancer (1,679 new cases). Bolivia has been described as a highland country, with one-third of its territory in the Andes Mountains, and its largest cities are located in the highlands. The mountainous western region, which is one of the highest inhabited areas in the world, is an important economic and political centre.

Bolivia's geography includes the Eastern Andes Mountain Range (Cordillera Oriental), which runs roughly north to south through the country. To the east of this range are the lowland plains of the Amazon Basin, and to the west is the Altiplano, a highland plateau. The Altiplano includes Lake Titicaca, which Bolivia shares with Peru. This lake is the second-largest in South America and the highest navigable lake in the world.

Bolivia's western region is characterised by two great parallel mountain ranges: the Cordillera Occidental and the Cordillera Oriental. The Cordillera Occidental, along the border with Chile, contains active volcanoes and the Uyuni Salt Flat. The Cordillera Oriental includes the Cordillera Real, a section of impressive snow-capped peaks near La Paz, with some exceeding 6,000 metres (19,685 feet) in elevation.

Between these two ranges lies the Altiplano, a relatively flat plateau extending from southern Peru through Bolivia to northern Argentina. The Altiplano includes the Titicaca and Poopó lakes and basins, which have been important agricultural, economic, and cultural areas. The descent from the Cordillera Real to the eastern plains is extremely steep, passing through a heavily forested belt known as the Yungas.

In terms of cancer rates, Bolivia had an estimated incidence rate of 142.9 per 100,000 people in 2018, with a mortality rate of 87.5 per 100,000. Gallbladder cancer is the leading cause of cancer death in Bolivia, and the country has the highest incidence rate of this cancer type worldwide, with 14 per 100,000 people affected. This high rate may be related to specific types of indigenous ancestry.

Prostate cancer is the second most common cancer in Latin America and the Caribbean

Prostate cancer is a disease that affects the prostate gland, which is responsible for producing semen, the fluid that carries sperm. It typically affects older men, with age being a primary risk factor. Additionally, prostate cancer risk is higher among Black men and men with a family history of the disease.

In Latin America and the Caribbean, prostate cancer is a significant health concern, with the highest incidence rates observed in the Caribbean. The region has seen an overall increase in the incidence of prostate cancer, with rates rising from about 20 cases per 100,000 people in 1984 to around 55-60 cases per 100,000 in the 2000s in some countries.

While prostate cancer is a leading cancer type in Latin America and the Caribbean, it is important to note that other cancers, such as breast cancer and colorectal cancer, are also prevalent in the region. However, the specific incidence and mortality rates can vary between countries.

Breast cancer is the most common cancer in Latin America and the Caribbean

Breast cancer is a type of cancer that originates in the breast, typically affecting women and individuals assigned female at birth (AFAB). It occurs when cells in the breast mutate and become cancerous, leading to the formation of tumors. The most common form of breast cancer is invasive ductal carcinoma (IDC), which accounts for about 70% to 80% of all breast cancer diagnoses. IDC arises in the milk ducts and spreads to the surrounding breast tissue.

The risk of developing invasive ductal breast cancer increases with age, with two-thirds of IDC diagnoses occurring in women aged 55 and older. However, it is important to note that breast cancer can also affect younger women and, less frequently, men and individuals assigned male at birth (AMAB). Early detection through screening mammograms is crucial, as IDC can spread to lymph nodes and other parts of the body if left untreated.

In Latin America and the Caribbean, the incidence of breast cancer varies across countries. For example, Uruguay has the highest incidence rate in the region, with 263 cases per 100,000 people, while Guyana has the lowest, with 105 cases per 100,000 people. The lifetime risk of being diagnosed with cancer also differs significantly, ranging from 26% in Uruguay to 11% in Guyana.

While breast cancer is the most prevalent type of cancer in Latin America and the Caribbean, other common cancers in the region include prostate cancer and colorectal cancer. Lung cancer is the leading cause of cancer-related deaths, followed by colorectal cancer and prostate cancer. Infection-related cancers such as stomach, cervical, and liver cancer are also prevalent in the region.
