What Is The Way Forward For Earlier Diagnosis Of Breast Cancer
In the UK, the NHS Breast Screening Programme offers all women aged 5070 a regular mammogram.
However, although participation rates average more than 70% nationally, they vary dramatically across the regions, with lower rates in economically deprived, inner-city areas.
There is a need to improve participation in breast screening programmes, particularly in socio-economically deprived areas.
Another 2018 study at Queen Marys, funded by Barts Charity, also indicated that breast cancer is still seen as a white womens disease.
While breast cancer incidence is lower among black women in the UK, survival rates are also lower, which may correlate with a reduced level of awareness about the prevalence of breast cancer among black women.
The report references the whiteness of the media coverage of breast cancer.
Smith says: Screening recommendations are designed to apply to most of the target population of women in a specific age group.
Mammography is less sensitive in women who have such significant mammographic breast density that a breast cancer cannot be seen, and for these women supplemental imaging with ultrasound or MRI can overcome the mammographys limitations in imaging very dense breast tissue.
The same limitation applies to women with an inherited predisposition to developing breast cancer because their risk is higher at an earlier age, when breast tissue is dense, but also mammography is less sensitive than MRI in these women when they are older.
Target Values And Their Definition
Since none of the identified studies addressed the mortality rate or the difference in mortality rate contributed by supplemental breast ultrasound, surrogate parameters, namely the assessment criteria of diagnostic tests, the additional relative and absolute rates of detected cancers compared to mammography and tumor size and lymph node negative status were used as target values. Negative predictive value, sensitivity and specificity of breast ultrasound were only computed if the follow-up period continued as long as the screening interval, thus permitting the identification of false-negative findings.
The risk of adverse impacts for the women examined was quantified using the number of biopsies performed due to breast ultrasound findings. The positive predictive value for biopsies with malignant histological findings characterizes the number of unnecessary biopsies induced by false positives.

We deliver care independent of insurance, so you wont have to worry about copays and coinsurance to seek advice about signs of breast cancer or any other health concerns that you have.
Breast Cancer Risk Factors
Women are considered to be at average risk of breast cancer if they do not have known risk factors, such as genetic mutations or a family history of breast cancer.
Those who have these risk factors are considered to be at a higher lifetime risk of developing breast cancer. More regular screening is required to monitor this higher risk.
Risk factors that put you at higher risk are detailed below. Having any of these risk factors means you should get a mammogram and breast MRI annually starting at 30. A medical professional can help you assess your risk if youre unsure.

What Is Breast Cancer
As mentioned previously, breast cancer refers to the abnormal growth of cancer cells in different parts of the breast.
These cells usually form a tumor which can be felt as a lump, or can be seen through an X-ray.
However, it is important to note that most breast lumps are benign, and not cancerous.
Although these tumors display abnormal growth, they are not life threatening and do not spread outside the breast.
Nevertheless, the presence of some types of benign lumps increase the risk of acquiring breast cancer.
Hence, any change in the breast should be properly examined by a health care professional to determine whether its cancerous or not, along with its implications and potential risk.
Mammography In The Early Detection Of Breast Cancer
Screening mammography is the best early detection method for reducing the number of deaths associated with breast cancer . Mammography is generally not undertaken in patients under 40 years of age , however women older than 40 should have mammograms every two years. Women with other risk factors such as a strong family history, gene anomalies or previous breast cancer may have mammograms at an earlier age or be monitored more closely.
Screening mammography is the best early detection method for reducing the number of deaths associated with breast cancer. For every 10,000 women aged 50-69 years screened over a 10 year period, mammograms would be expected to prevent between 10 and 20 deaths from breast cancer.
The benefits of screening mammography are different depending on the age of the woman. Younger women have denser breast tissue, which make breast changes harder to detect. In addition, as the occurrence of breast cancer increases with age, older women are more likely than younger women to have developed breast cancer so more cancers are detected with mammography in older women.
In Australia, the National Breast Cancer Centre recommendations regarding screening mammograms are as follows:
Women who are at increased risk of developing breast cancer, such as those with a strong family history, should have an individualised surveillance program established in consultation with their doctor.

Early Detection Of Breast Cancer By Mammography Screening
This fact box will help you to weigh the benefits and harms of early detection of breast cancer by mammography screening. The information and numbers are based on the best scientific evidence currently available.
This fact box was developed by the Harding Center for Risk Literacy.
Breast cancer develops when abnormal cells multiply in an uncontrolled manner and gradually turn into lumps or growths in the breast tissue. Cancer cells can infiltrate healthy tissue and metastasize . Factors such as age, family history, and hormonal influences can affect the development of breast cancer. It is assumed that about 8 out of 100 cases of breast cancer are hereditary and can be traced back to the so-called breast cancer genes BRCA1 and BRCA2 .
Breast cancer is the most common cancer affecting women in Germany, with about 70,000 new cases each year .
Early detection targets people who do not show symptoms of a particular disease . The aim is to detect and treat breast cancer at an early stage in order to increase chances of recovery.
A mammography is an X-ray examination of the breast in which two X-rays are taken from different angles. These X-rays are each assessed independently by two doctors for signs of abnormalities that may be cancerous .
Alternative early detection procedures include ultrasound and magnetic resonance imaging of the breast. It remains unclear whether these procedures help lower the risk of dying from breast cancer .
If Breast Cancer Strikes: Multidisciplinary Breast Clinic Offers Help And Hope
A breast cancer diagnosis leaves you with questions, decisions, and anxiety. The Multidisciplinary Breast Clinic at the Regional Cancer Center helps newly diagnosed breast cancer patients or patients looking for a second opinion for their treatment options. Patients can be referred by their physician or they can contact a breast cancer navigator for a self-referral.
Dr. Ferrari says clinic assessments give patients what they need to help them make informed decisions about their treatment.
Many recent advances in the diagnoses and treatment of breast cancer require close collaboration between cancer specialists, who have different areas of expertise, Dr. Ferrari explains. The clinic brings these specialists together to meet with and evaluate each patients case.
A medical oncologist, radiation oncologist, and surgeon as well as a medical team together evaluate each persons case, engaging them and their family in the treatment plan.
Typically, this kind of process might take weeks to develop — but we have all the experts in one place, says Dr. Ferrari. Local women have everything they need for screening, diagnosis and fighting breast cancer right here, close to home, at the Regional Cancer Center. That means the plan is complete in a single day, and your treatment begins quickly.

Why Are Some Cancers Diagnosed Late
There can be several reasons for delays in cancer diagnosis, for example:
- People might not be aware of possible cancer signs and symptoms, such as feeling tired for no reason, or having a cough that doesnt go away.
- People might struggle to get an appointment at a convenient time or be worried about taking up doctor time.
- Some people might put off speaking to their GP because of worries about what they might find.
- There can be delays in referring patients for tests, or in getting an appointment at the hospital.
- Not all diagnosis journeys are straightforward. Doctors might investigate other possibilities before making a cancer diagnosis.
When it comes to your body, remember youre in charge. If you do spot something unusual, dont put it off. Speak to your doctor, even if its something youve mentioned before. In most cases it wont be cancer but if it is, finding it early can make a real difference.
In the UK, national screening programmes can help diagnose cancers at an early stage, when treatment is more likely to be successful. Cancer screening is for people without symptoms, so if youve noticed a change, dont wait for screening. Tell your doctor as soon as possible.
Breast Cancer Burden In Ssa
Breast cancer is the most common female cancer globally, with an estimated 1.67 million incident cases in 2012 . The highest age-standardised incidence rates are observed in North America, Australia, New Zealand, and Northern and Western Europe and there is an observed correlation between GDP and incidence rates . However, while incidence has plateaued and is decreasing in many high-income countries, it continues to increase in low- and middle-income countries due in large part to the epidemiological transition described earlier . Whereas breast cancer mortality in many high-income countries has decreased significantly over the past 25years due to improvements in awareness, early detection and treatments , it is now the leading cause of death from cancer in LMICs . The mortality-to-incidence ratio is higher among countries with lower GDPs , and the gap between high and low-income countries with respect to breast cancer mortality is expected to widen if current epidemiological trends continue .

South Central Cancer Centers New Cancer Specialist Talks About The Importance of Early Detection of Breast Cancer
The very early breast cancers have a 97 to 100 percent chance of cure, but once it spreads to the lymph nodes or elsewhere the chance of cure goes down significantly, Sandeep Singh, MD
Breast cancer is the most common form of cancer in women. Within the United States there are over 2.5 million breast cancer survivors. This is because most breast cancer can be completely cured if it is detected early. There is a 1-in-8 chance that a woman will have invasive breast cancer sometime during her life, so regular screenings are very important for early detection and survival of the disease.
Sandeep Singh, MD Medical Oncologist/Hematologist South Central Cancer Center
Sandeep Singh, MD, the new Hematologist/Medical Oncologist at South Central Cancer Center recently completed a fellowship at Mayo Clinic in Rochester Minnesota, before moving to Laurel and accepting the position of Medical Director of the Cancer Center. He said, According to the Mississippi State Department of Health, women in Mississippi who are likely to have advanced stages of breast cancer include minorities, elderly women and the medically underserved. This reflects differences in access to screenings and access to information about the symptoms of breast cancer. However, women in those categories are not the only ones who I see with breast cancer.
Introduction To The Early Detection Of Breast Cancer
The early detection of breast cancer in women is important for the effective management of the disease. Although there is no current treatment to prevent breast cancer, early detection of the disease can lead to an excellent outcome.
Early detection methods for breast cancer include screening mammography, clinical breast examination and breast awareness. Breast self-examination, a technique taught to women in the past, is no longer recommended as it has not been shown to improve outcomes.

Living Beyond Breast Cancer
Initiatives such as National Breast Cancer Awareness Month appear to have had a great impact. Despite the rise in new breast cancer cases, breast cancer deaths in the USA have dropped an astounding 40% during the nearly 30 years between 1989 and 2017.
No matter what, living beyond breast cancer is possible when we lean on God for strength.
As my own family experienced recently, the threat of cancer is real. However, during that trial, the words of Jesus were especially comforting:
These things I have spoken to you, that in Me you may have peace. In the world you will have tribulation but be of good cheer, I have overcome the worldJohn 16:33
Disease Stage At Diagnosis
In this review, 32 studies were identified that reported the stage at diagnosis of histologically proven breast cancer in SSA countries . Most of these were from Western Africa, while there were fewer studies available from Central Africa. Some countries had no data available, while others were over-represented. The majority were retrospective studies of medical records with sample sizes ranging from 34 to 1361. Advanced stage at diagnosis was extremely high and ranged from 42.2% of cases among women attending a tertiary hospital in South Africa, to 98% of women attending a medical centre in Tanzania. In one South African study that compared disease stage between black and white women, disease was more advanced among black women . A Nigeria study reported a mean delay of 11.2months between symptom onset and attendance at a healthcare facility, and 80% of women in the study had advanced stage disease . Delay between symptom onset and medical consultation is common among women in SSA, and is frequently greater than 6months . This suggests that improving early detection of breast cancer among women in SSA could have a considerable impact on stage at diagnosis, and confer improved prognoses and treatment options.

Group Of Women Examined
The systematic search yielded studies in which breast ultrasound was used as a supplemental examination following mammographic interpretation. Moreover, of the group of asymptomatic women with negative mammographic results, women with breast tissue density went on to be examined by ultrasound. The only exception is the study performed by Leconte et al., 2003 , where 3% had palpable findings .
The fraction of these women relative to all women screened within the specified period was reported in two studies at 36% and 35.8% . The size of the study populations ranged from n = 1517 to n = 13547, with mean n = 5118.
Clinical Breast Examination In The Early Detection Of Breast Cancer
Clinical breast examination refers to examination by a trained health professional of a womans breasts. The woman will not normally have noticed any breast changes before the examination. The examination is focused on detecting changes to the breasts, such as skin changes, nipple discharge, lumpiness, or changes in size or shape.
There is no clear evidence to suggest that clinical breast examination is an effective method of early detection of breast cancer in women who are already undergoing regular screening mammograms. In women who do not have regular mammograms, clinical breast examination may be useful.
