Cervical cancer worldwide

LANCET

  • There were 570,000 cases and 311,000 deaths worldwide last in 2018.
  • The average age of diagnosis was 53.
  • In 42 low-resource countries, it was the most common cancer in women.
  • A third of the cervical cancer burden fell on China and India together.

 

 


Inequities in cervical cancer care in indigenous Peruvian women (about 25% of Peru’s population is indigenous)

Inequities in cervical cancer care in indigenous Peruvian women
May, 2019
“…Lima, is home to the country’s National Institute of Cancer (INEN) and has substantially lower rates of cervical cancer than elsewhere in the country, partially due to higher socioeconomic status and better access to screening and specialised care./…..”
“…..When informed she must travel to INEN for care, a patient from the Andean region told us: “I started crying, begging the doctors, ‘I don’t even have enough money to eat. I don’t have a job. How am I going to travel to Lima where I don’t even have family to stay with?’”

Similar to several participants, a woman from the Amazon region, who had SIS and was referred to INEN for free care, did not have the means to travel and sought local traditional herbal remedies, remaining in pain for over a year without treatment. Of the women who were able to travel to Lima, finding accommodation was a substantial barrier to care…….”

Betel quid chewing & cancer

MizzumaBurmese

“…..People start to enjoy the betel quid chewing starting in the
adolescence, and is associated with alcohol drinking and smoking. The
practice can lead to oral cancer.

In 2017, 67 (22 percent) out of 307 cancer patients in Taungoo public
hospital were suffering from head and neck cancer. Among them, 41 were
males and 26 were females. Males were aged in average 59.2 years
(range 36-81 years) and females were about 58.7 years old (range 19-86
years). Most of the cancers were in the oral cavity (34.3 percent),
followed by larynx (25.4 percent), oropharynx (11.9 percent),
nasopharynx (11.9 percent), hypopharynx (10.4 percent), lips (4.5
percent), and nose (1.5 percent).

As for social factors, about 20 patients (30 percent) had the habit of
betel quid chewing, 19 patients (28 percent) chewed betel quid and
smoked, and 19 patients (28 percent) chewed betel quid, smoked, and
drank alcohol…..”

Betel Quid with Tobacco (Gutka)

 See the source image

Betel quid is a combination of betel leaf, areca nut, and slaked lime.

In many countries, tobacco is also added, and the product is known as gutka, ghutka, or gutkha.

Other ingredients and flavorants are also added according to local preferences and customs (e.g., sweeteners, catechu, or spices such as cardamom, saffron, cloves, anise seeds, turmeric, and mustard).

Gutka is commercially available in foil packets and tins and is consumed by placing a pinch of the mixture in the mouth between the gum and cheek and gently sucking and chewing. The excess saliva produced by chewing may be swallowed or spit out.2

Use

  • Betel quid and gutka use is reported to have stimulant and relaxation effects.2
  • Global estimates report that up to 600 million men and women use some variety of betel quid.2
  • Betel quid with or without tobacco is widely used in the Indian subcontinent (i.e., Bangladesh, India, Pakistan) as well as throughout Asia and the Pacific region (e.g., Cambodia, China, Indonesia, Malaysia, Philippines, Taiwan, Thailand).1,2,3,5

Health Effects

The following conditions have been associated with betel quid/gutka use:

Precancerous conditions

  • Oral precancerous lesions, including erythroplakia (a reddened patch in the mouth) and leukoplakia (a white patch on the mucous membranes in the mouth that cannot be wiped off).2,6
  • Oral submucous fibrosis (OSF), a precancerous lesion that stiffens the soft pink tissue that lines the inside of the mouth (i.e., oral mucosa).

Cancer

  • Oral cancers—predominantly carcinomas of the lip, mouth, tongue, and pharynx2,6,8
  • Cancer of the esophagus2

Other health effects

  • Reproductive health outcomes such as increased risk of having a low birth-weight infant7
  • Nicotine addiction4

  • 65% cancer deaths
  • 46% Living with cancers

  • Tobacco kills about six million people globally each year, according to the World Health Organization, and 300,000 to 400,000 of them are Russians.
  • About 33 percent of Russian adults use tobacco products.

** Cancer statistics in China, 2015: China is facing 2.8 million deaths just in in 2015, with lung cancer crowning the top of the list of cancer cases.

CA: A Cancer Journal for Clinicians

With increasing incidence and mortality, cancer is the leading cause of death in China and is a major public health problem. Because of China’s massive population (1.37 billion), previous national incidence and mortality estimates have been limited to small samples of the population using data from the 1990s or based on a specific year. With high-quality data from an additional number of population-based registries now available through the National Central Cancer Registry of China, the authors analyzed data from 72 local, population-based cancer registries (2009-2011), representing 6.5% of the population, to estimate the number of new cases and cancer deaths for 2015. Data from 22 registries were used for trend analyses (2000-2011).

The results indicated that an estimated 4292,000 new cancer cases and 2814,000 cancer deaths would occur in China in 2015, with lung cancer being the most common incident cancer and the leading cause of cancer death. Stomach, esophageal, and liver cancers were also commonly diagnosed and were identified as leading causes of cancer death.

Residents of rural areas had significantly higher age-standardized (Segi population) incidence and mortality rates for all cancers combined than urban residents (213.6 per 100,000 vs 191.5 per 100,000 for incidence; 149.0 per 100,000 vs 109.5 per 100,000 for mortality, respectively). For all cancers combined, the incidence rates were stable during 2000 through 2011 for males (+0.2% per year; P = .1), whereas they increased significantly (+2.2% per year; P < .05) among females. In contrast, the mortality rates since 2006 have decreased significantly for both males (−1.4% per year; P < .05) and females (−1.1% per year; P < .05). Many of the estimated cancer cases and deaths can be prevented through reducing the prevalence of risk factors, while increasing the effectiveness of clinical care delivery, particularly for those living in rural areas and in disadvantaged populations.
