Report on Ovarian Cancer: Epidemiology, Symptoms, Diagnosis, and More

This report provides a detailed overview of ovarian cancer, addressing its pathological conditions, epidemiology, symptoms, and diagnosis. It highlights that ovarian cancer is a leading cause of mortality among women, particularly those aged 35 to 74, with epithelial ovarian cancer being the most common type. The report discusses the challenges in understanding the etiology of ovarian cancer due to the variability of clinical profiles and non-specific symptoms, noting the multifactorial developmental origin involving genetic abnormalities, hormonal factors, or fallopian tube involvement. It also examines the epidemiology of ovarian cancer, noting variations in incidence rates based on geographic distribution and genetic susceptibility. Furthermore, the report emphasizes that while bloating of the stomach is a common symptom, it is not specific to ovarian cancer and can be associated with other conditions like Celiac disease, liver disease, renal failure, intestinal parasitic infection, and Gastroparesis. The report concludes that bloating alone does not indicate the initiation of ovarian cancer.

Abstract
The following paper discusses the pathological conditions of ovarian cancer, one of the epidemic
cause of women deaths annually with a focus on its epidemiology, symptoms and diagnosis. It
also discusses that bloating of stomach, a symptom of ovarian malignancy does not always
indicate cancerous progression; it can also be associated with many disorders which are enlisted
in the following paper.

Introduction
Overview of Ovarian Cancer
Ovarian cancer has become an epidemic in today’s world. Ovarian cancers are the
common leading cause of mortality among women in United States, affecting 1 in 75 women
among the female population, as estimated by the American Cancer Society. The estimated
chance of mortality is 1 in 100 among females (Glance, 2013). Women aged between 35 and 74
years are the most common victims of this dreadful disease. The most common type predominant
among women is the epithelial ovarian cancer, 70% of whose diagnosis occurs in the later stages
of cancer progression (Desai et al., 2014). The disease prognosis is dependent on the stages of
progression of cancer, therefore there is a lack of a common method of diagnosis and treatment.
The clinical profile of women diagnosed with ovarian cancer shows a heterogeneity of
symptoms, which make prognosis confounding and difficult. Conventional diagnostic methods
include surgical removal of the malignant ovaries and chemotherapy post-surgery. Bloating of
stomach, a common symptom in ovarian cancer is not specific to the pathology. Bloated
condition is associated with other different pathologies like Celiac disease, liver disease, renal
failure, intestinal parasitic infection and Gastroparesis.
Discussion
Etiology of Disease
The variability of the clinical profile and non-specific symptoms causes difficulty in
clearly understanding the etiology of ovarian cancer. Ovarian cancers are histologically divided
into many subtypes like epithelial ovarian cancer, stromal and germinal ovarian cancer.
Epithelial ovarian cancer is the most predominant subtype diagnosed among women at higher

grades of development. Diagnosis of any of these subtypes occurs at later stages, mostly stage III
and IV of the progression, so early steps of developing the cancer is not clearly known. The
development of ovarian cancer depends on a variety of factors as hypothesized in recent years.
The multifactorial developmental origin of the ovarian cancer can be traced to the accumulation
of genetic abnormalities or mutations during ovulation, hormonal factors causing uncontrolled
cellular buildup on the epithelium of ovary forming a tumor or from the fallopian tube itself
(Wentzensen et al., 2016). Many cases of diagnosis have shown the involvement of fallopian
tube in progression of epithelial ovarian cancers. The disease presents with heterogeneity in
clinical profile and its developmental ways, therefore the exact etiology remains further to be
elucidated.
Epidemiology of Disease
The ovarian cancers have been reported with high incidence rates depending on wide
variations of geographic distribution. In United States, higher incidence rates have been among
the White population and lowest incidence occurs among the Black population and the Asians
(Reid, Permuth & Sellers, 2017). Higher incidences of the ovarian cancers have been observed in
developed countries as compared to rural regions. High predisposition of the cancerous
progression has been attributed to the genetic susceptibility. People with a family history of
ovarian cancer are at increased risk of developing the disease at an earlier age; the first
generation relatives being most susceptible. High mutation rates of BRCA1b and BRCA2 have
associated with the increased pathogenesis of ovarian cancers. These genetic factors account for
around 10% of this gynecological cancer with a high lifetime risk for the women (Reid, Permuth
& Sellers, 2017).

Chief Symptoms
Ovarian cancer, be it any histological subtype, is better detected and diagnosed at later
developmental stages, mainly stage III and IV. Early stages of development are difficult to detect
as the disease presents non-specific symptoms. Few women have been diagnosed at early stage
of progression, within one month as detected depending on the size of the tumor. Based on the
diagnosis of these women, early signs and symptoms have been assumed as risk factors for
disease progression to later stages. Frequent menstrual cycles within a month, irregular bleeding
with abdominal cramps similar to menstruation have been assumed as early signs of malignancy
(Ebell, Culp & Radke, 2016). Loss of appetite and abdominal fullness, disorder bowel motions,
increasing back pain with discomfort, a bloated stomach are some of non-specific symptoms
which are regarded as benign by the women and hence increases the risk of developing the
disease. The urge to frequently urinate is also a significant symptom to be considered.
Diagnosis and Treatment
Diagnosis of the ovarian cancers commonly occur in the advanced stages, stages III and
IV since the early symptoms are not intense to cause easy detection. Diagnosis at earlier stages is
difficult. So, there is no reliable and consistent diagnostic tests available; still women at
increased risk of ovarian cancer are recommended some screening tests to determine the
certainly of their inheriting the malignancy. An interactive session is held with the consulted
gynecological oncologist to determine the prevalence of prior medical history or familial genetic
history. Imaging tests are initially recommended to those women who are suspected to have a
malignant predisposition in ovaries. Ultrasound therapy, particularly transvaginal
ultrasonography is offered to suspected women and also to those who are at early stages of
detection. Through sound waves, an entire histological image of the ovary is taken which shows

if there is an initiation of malignancy. Genetic testing and genetic counseling are also efficient
methods of screening for ovarian cancers. This helps to know the genetic susceptibility in cases
of familial history (Liang et al., 2018). Blood tests like CA-125 testing is efficient for screening
of ovarian cancers. A mucin-16 protein is produced by ovaries, whose level increases to a higher
level in cases of gynecological cancers. The CA-125 screening test determines the level of this
protein, a measure to determine the risk of developing ovarian malignancies (Suidan et al.,
2014). Once any of these screening tests turn out positive for the suspected women, a CT scan is
recommended for a higher accuracy. Finally, a more confirmative test is biopsy, where a minute
portion of the tumor is taken and observed under microscope to determine its malignancy.
Surgical removal increases the survival rate in women with advanced stages of progression.
Disease Management
Improvement of treatment is better achieved through medication schemes post-surgery in
women with advanced progression of ovarian cancer. A treatment management of dose
dependent strategy have shown positive results. A combination of paclitaxel with a dosage of
80mg and carboplatin on a basis of weekly intake has been an improvement in increasing the
survival rate of the women who have undergone surgical treatment (Sue et al., 2018).
A predominant but non-specific symptom of ovarian cancer is bloating of stomach, a
condition when a person feels abdominal fullness and suffers from loss of appetite. This bloated
condition is common to a number of pathological conditions, some of which are Celiac Disease,
Liver Disease, Kidney Failure, Intestinal infestation with parasitic infection namely Ascaris
lumbricoides and Gastroparesis where emptying of stomach is much delayed producing a bloated
condition.

The autoimmune Celiac Disease occurs due to gluten sensitivity in individuals when they
consume gluten containing wheat, rye or barley. Gluten consumption damages the microvilli
lining the intestines, which are involved in nutrient absorption. This delays the emptying of
stomach causing a bloated condition with discomfort.
Liver Disease often accompanies ascites which is accumulation of fluids in the abdomen.
This produces a distention of the waist and a bloated stomach.
Kidney failure or chronic kidney disease is associated with fluid accumulation between
the renal tubes, in turn leading to abdominal fluid accumulation. This shows a bloating of
stomach with distension causing much discomfort.
Intestinal infection by parasites, particularly cestodes and nematodes are a major cause of
bloating of stomach. Parasitic worms like tapeworm (Ascaris lumbricoides) causes gastric
infection. This causes loss of appetite due to feeling of bloated stomach, also causing loss of
weight.
Gastroparesis occurs due to impairment of intestinal muscles; the muscles lose motility
and cannot move the food particles down the digestive tract. As a result, it takes enormous time
for the stomach to empty its contents, causing a bloating condition.
Conclusion
Ovarian cancers, along with its histological subtypes are the leading cause of deaths
annually among women. Among the symptoms, bloating of stomach cannot specify the
susceptibility of ovarian cancer; this symptom has been observed for many other diseases and
syndromes. In all such cases, bloating does not lead to development of ovarian malignancies;

therefore it may be concluded that bloating alone does not indicate initiation of cancer in
gynecological cases, it may be due parasitic infections and other disorders mentioned above.
