Endometrial Cancer Simplified: Understanding Causes, Symptoms, Diagnosis, Treatment
Endometrial cancer initiates as an abnormal cell growth within the uterus, the pear-shaped organ where fetal development occurs.
It arises when the endometrium, a distinctive tissue lining the uterus, undergoes cancerous changes.
Most uterine cancers stem from Endometrial cancer, which is also the most commonly diagnosed gynecologic cancer.
According to John Hopkins Medicine, approximately 50,000 women in the United States receive this diagnosis annually.
Endometrial cancer is frequently misidentified as Endometriosis Cancer due to improper wording and misunderstanding.
Given that it is the predominant type of uterine cancer, it is often colloquially termed uterine cancer.
The article discusses the various aspects of Endometriosis cancer, such as symptoms, stages, causes, diagnosis, and treatment.
What is Endometrial cancer
The uterus is coated with a unique tissue known as the endometrium.
Endometrial cancer happens when cells grow abnormally and can invade or spread to other body parts, which is different from uterine sarcoma.
About 80% of Endometrial cancers come from cells that make glands in the uterus lining, known as adenocarcinomas.
Early detection significantly enhances the curability of Endometrial cancer.
Symptoms of Endometrial cancer
Endometrial cancer is frequently detected early due to the manifestation of symptoms.
The initial sign is often irregular vaginal bleeding.
Bleeding or discharge not related to menstruation
Over 90 percent of women diagnosed with Endometrial cancer experience abnormal vaginal bleeding.
It refers to bleeding or discharge that occurs outside the regular menstrual cycle.
This symptom can be a significant indicator of Endometrial cancer.
Postmenopausal bleeding
One notable symptom of Endometrial cancer is bleeding that occurs after Menopause.
Any such occurrence should be promptly investigated by a healthcare professional.
Difficult or painful urination
Endometrial cancer may present with symptoms related to the urinary system, such as difficult or painful urination.
If one experiences any discomfort or pain during urination, it is crucial to seek medical attention.
This will help identify the cause, and there is a possibility that it could be associated with the cancer.
Pain during intercourse
Another symptom associated with Endometrial cancer is pain during sexual intercourse.
This discomfort may indicate changes in the reproductive organs and should be discussed with a healthcare provider for further evaluation.
Pain and/or mass in the pelvic area
Endometrial cancer may cause pain or the presence of a palpable mass in the pelvic region.
These symptoms can be indicative of the tumor affecting the surrounding tissues.
Persistent pelvic pain requires evaluation by a medical professional to identify its root cause.
This investigation should consider possibilities such as Endometrial cancer, especially if an unusual mass is discovered.
Stages
Upon detecting cancer through tests, the doctor will evaluate the tumor’s grade.
Then, the cell division rate and the cancer’s anticipated growth speed are determined.
A higher-grade tumor indicates a greater likelihood of rapid growth and potential spread to other body parts.
The cancer’s stage influences the optimal treatment plan, in part indicating the extent of its spread.
When staging Endometrial cancer, doctors may utilize the following definitions:
Stage 1: The cancer has extended from the inner lining to the endometrium. It may potentially reach the myometrium, the middle layer of the uterine wall
Stage 2: The tumor has progressed to involve the cervix
Stage 3: The tumor has advanced beyond the uterus, affecting nearby tissues such as the vagina or a lymph node
Stage 4: The cancer has reached the bladder or intestine and may have spread to other regions like the bones, liver, or lungs
Causes
The precise causes of most cases of Endometrial cancer are not yet fully understood.
Certain risk factors, including obesity and hormonal imbalances, have strong associations with this type of cancer.
In Endometrial cancer, most cancer cells feature receptors for Estrogen on their surfaces.
The interaction between these receptors and the hormones can result in heightened growth of the endometrium.
This excessive growth can progress towards abnormal conditions, eventually leading to the development of cancer.
Many of the identified risk factors for Endometrial cancer influence the delicate balance between Estrogen and Progesterone in the body.
Obesity
Obesity is a significant risk factor for Endometrial cancer, linked to hormone changes, particularly affecting Estrogen levels.
Before Menopause, a woman’s ovaries predominantly produce Estrogen.
Elevated fat tissue increases Estrogen levels, thereby raising the risk of Endometrial cancer.
Endometrial cancer is twice as common in overweight women (BMI 25 to 29.9).
Additionally, it is over three times as prevalent in obese women (BMI > 30) compared to those with a healthy weight.
Hormone factors
Hormone factors also contribute to the development of most Endometrial cancers.
The balance between Estrogen and Progesterone, the two main female hormones ovaries produce before Menopause, plays a crucial role.
This hormonal balance fluctuates throughout the menstrual cycle, governing monthly periods and maintaining the health of the endometrium.
An imbalance, with an increased presence of Estrogen, heightens a woman’s risk for Endometrial cancer.
Personal history of breast cancer
A personal history of breast cancer increases the risk of developing Endometrial cancer.
Shared risk factors contribute to heightened susceptibility.
This underscores the need for careful monitoring and preventive measures, especially considering hormonal influences.
Personal history of ovarian cancer
Having a personal history of ovarian cancer is a risk factor associated with an increased likelihood of Endometrial cancer.
Shared genetic or hormonal factors may contribute to the elevated risk despite originating in different reproductive organs.
Careful monitoring and early detection strategies are important for individuals with a history of ovarian cancer.
This is important as it addresses the potential risk of Endometrial cancer.
Endomteriosis vs. Endometrial cancer
Endometriosis and Endometrial cancer are frequently mistaken due to their similar names, though they are distinct conditions.
It’s important to understand that Endometriosis isn’t cancer, and having it doesn’t mean you’ll get Endometrial cancer.
While Endometriosis can be intensely painful, it is not life-threatening.
These conditions share their impact on the tissue forming the inner lining of the uterus, known as the endometrium.
Endometriosis involves the growth of tissue resembling the endometrium outside the uterus.
The onset of Endometrial cancer occurs when there is an uncontrolled growth of the uterine lining, leading to the formation of a tumor.
The cancer cells from this tumor can spread to other body parts, giving rise to additional tumors.
Endometrial cancer is less prevalent than Endometriosis.
It nevertheless remains the most frequently diagnosed gynaecological cancer in women in the United States.
Can Endometriosis cause cancer
Because Endometriosis is connected to how cells and hormones function, it might seem logical to consider a link to cancer.
However, having Endometriosis does not necessarily heighten the risk of cancer.
Surprisingly, Endometriosis does not increase the risk of most other gynecological cancers, including Endometrial cancer, despite the similarity in names.
Moreover, there is no genetic trait associated with Endometriosis that could lead to cancer.
Certain rare ovarian cancers (like clear cell and endometrioid types) are more common in women with Endometriosis.
The overall risk of developing these specific ovarian cancers in women with Endometriosis is below 1%.
Treatment
The choice of treatment depends on the cancer stage.
Surgery is usually the first step, and additional therapy may be needed.
Treatment options may include various interventions.
Doctor will decide on the best treatment for Endometrial cancer based on the following:
- Health and medical history
- How far the disease has spread
- Ability to handle specific medications or procedures
- Expectations for the disease’s progression
Surgery
Surgery typically involves a hysterectomy, removing the uterus, fallopian tubes, and ovaries.
If done before menopause, this results in the cessation of menstruation and the inability to conceive.
Radiation therapy
Radiation therapy employs powerful beams to destroy cancer cells by damaging their DNA.
External radiation may target the pelvis and affected areas.
It can be used to shrink tumors before surgery or eliminate remaining cancer cells post-surgery.
Chemotherapy
Chemotherapy uses drugs to kill or remove cancer cells alone or in conjunction with radiotherapy.
It can slow the progression of late-stage cancer and extend life expectancy.
Targeted therapy
Targeted therapy uses substances to disrupt specific cancer cells, hindering blood vessel growth or blocking signals for excessive cell reproduction.
The goal is precise intervention in cancer development.
Hormone therapy
Certain hormones promote cancer cell growth. Hormone therapy involves blocking or removing these hormones.
Progestin, Tamoxifen, and other agents are crucial in hormone therapy, blocking cancer-promoting hormones.
Conclusion
Endometrial cancer starts as abnormal cell growth in the uterus, specifically in the endometrium.
Early detection is crucial, often through surgery, as indicated by symptoms like irregular bleeding.
Symptoms also include abnormal bleeding, postmenopausal bleeding, painful urination, discomfort during intercourse, and pelvic pain or mass, providing crucial diagnostic indicators.
It distinguishes Endometriosis from Endometrial cancer, clarifying that Endometriosis is not cancerous.
Key risk factors include obesity, hormonal imbalances, and a personal history of breast or ovarian cancer.
Staging determines the severity of Endometrial cancer, influencing treatment choices.
Surgery, typically a hysterectomy, is often the first step, followed by personalized treatments like radiation, chemotherapy, targeted therapy, and hormone therapy.
These interventions are customized based on individual cases.
So, the article has all you need to know about endometrial cancer, like its symptoms, stages, causes, and how it’s treated, to help you manage it better and prevent it.
Frequently Asked Questions
What is Endometrial cancer?
Endometrial cancer originates from abnormal cell growth in the uterus lining. It happens when cells in the uterus lining change, grow too much, and form a lump. These cells might also spread to other body parts and create lumps there. Regular medical check-ups are vital for accurate diagnosis and monitoring.
Is Endometriosis a type of Cancer?
No, Endometriosis is not a type of cancer. While it may share symptoms with cancer, Endometriosis itself is a non-cancerous condition. Endometriosis involves the abnormal growth of tissue resembling the uterus lining outside the uterus. Unlike cancer, it does not involve the uncontrollable spread of malignant cells.
Can Endometriosis turn into Endometrial Cancer?
Endometriosis itself is not cancer. Nevertheless, in rare cases, some types of ovarian cancer may arise in women with a history of Endometriosis. Regular medical monitoring and awareness of symptoms are important for early detection and intervention if needed.
What are the treatment options available for Endometrial cancer?
Treatment may involve surgery, chemotherapy, and targeted therapies. A personalized approach, considering the type and stage of cancer, is crucial, with the goal of maximizing outcomes and preserving fertility when possible.
