Which Types Of Breast Cancers Do Well With Less Chemotherapy
Research in the last two decades has shown that two types of breast cancer respond well to less-intensive chemotherapyor none at allin some cases:
- HR-positive: This is the largest breast cancer subtype, accounting for as many as 75% of all cases. The majority of women diagnosed with this subtype of breast cancer have no lymph node cancer at the time of diagnosis. Both for these women and many with positive lymph nodes, hormonal therapy is the most important treatment, and chemotherapy may not be needed, Dr. Winer says.
- HER2-positive. This aggressive breast cancer makes up 15 to 20% of breast cancer cases. Once a deadly disease, even in its early stages, it is now curable in more than 90% of cases, Dr. Winer explains. In early HER2-positive cancers, weve found that very limited courses of chemotherapy can be just as effective as treatment that is more extreme, he says.

The Tnm System Is Used To Describe The Size Of The Primary Tumor And The Spread Of Cancer To Nearby Lymph Nodes Or Other Parts Of The Body
For breast cancer, the TNM system describes the tumor as follows:
Tumor . The size and location of the tumor.
Tumor sizes are often measured in millimeters or centimeters. Common items that can be used to show tumor size in mm include: a sharp pencil point , a new crayon point , a pencil-top eraser , a pea , a peanut , and a lime .
- TX: Primary tumor cannot be assessed.
- T0: No sign of a primary tumor in the breast.
- Tis: . There are 2 types of breast carcinoma in situ:
- Tis : DCIS is a in which cells are found in the lining of a . The abnormal cells have not spread outside the duct to other tissues in the breast. In some cases, DCIS may become that is able to spread to other tissues. At this time, there is no way to know which can become invasive.
- Tis : Paget disease of the is a condition in which abnormal cells are found in the skin cells of the nipple and may spread to the . It is not staged according to the TNM system. If Paget disease AND an invasive breast cancer are present, the TNM system is used to stage the invasive breast cancer.
Emerging Areas In Metastatic Breast Cancer Treatment
This is a promising time in metastatic breast cancer research. Many new treatments for metastatic breast cancer are under study and treatment is improving. Most of these new treatments are drug therapies.
Findings from clinical trials will determine whether or not these new treatments become a part of the standard of care for metastatic breast cancer.
Some treatments may even go on to be used for early-stage breast cancer care.

Breast Cancer Early Detection And Treatment Research
The Breast Specialized Programs of Research Excellence are designed to quickly move basic scientific findings into clinical settings. The Breast SPOREs support the development of new therapies and technologies, and studies to better understand tumor resistance, diagnosis, prognosis, screening, prevention, and treatment of breast cancer.
The NCI Cancer Intervention and Surveillance Modeling Network focuses on using modeling to improve our understanding of how prevention, early detection, screening, and treatment affect breast cancer outcomes.
The Confluence Project, from NCI’s Division of Cancer Epidemiology and Genetics , is developing a research resource that includes data from thousands of breast cancer patients and controls of different races and ethnicities. This resource will be used to identify genes that are associated with breast cancer risk, prognosis, subtypes, response to treatment, and second breast cancers.
The goal of the Breast Cancer Surveillance Consortium , an NCI-funded program launched in 1994, is to enhance the understanding of breast cancer screening practices in the United States and their impact on the breast cancer’s stage at diagnosis, survival rates, and mortality.
There are ongoing programs at NCI that support prevention and early detection research in different cancers, including breast cancer. Examples include:
How Pancreatic Cancer Defies Treatment
- University of California – San Diego
- Researchers describe how pancreatic cancer stem cells leverage a protein in a family of proteins that normally suppress tumors to instead do the opposite, boosting their resistance to conventional treatments and spurring growth.
Pancreatic cancer is the third deadliest cancer in the United States, after lung and colorectal, though far less common. It is also among the hardest to effectively treat, with pancreatic cancer stem cells quickly developing resistance to conventional and targeted treatments, such as chemotherapy and emerging immunotherapies. As a result, the 5-year survival rate for people diagnosed with pancreatic cancer is just 10%.
In a new paper, published January 18, 2023 in Nature Communications, an international team of scientists, led by researchers at University of California San Diego School of Medicine and the Sanford Consortium for Regenerative Medicine, reveal another way in which the most-resistant pancreatic cancer cells defy treatment by leveraging a member of a group of proteins that ordinarily might suppress tumors to instead help cancer cells evade therapy and grow more quickly.
Previous research has shown that pancreatic cancer treatment resistance is caused by differing responses to conventional agents, fueled by the heterogeneity of tumor cells — and in particular, stem cell characteristics that encourage therapy resistance.

Overcoming Disparities In Cancer Care Worldwide
Rugo concluded by noting the slow progress in resolving disparities in cancer care. There is a global initiative to improve breast cancer outcomes, most patients in the world do not have access to the therapies that patients do, she said, adding that the problem of access hits close to home as well. Even within the US, many patients dont have access they are the silent minority. Rugo cited a patient who discontinued her treatments because of the financial implications, without reaching out for help.
We need to reach out to our patients, Rugo said. We need to be vocal about tackling disparities in cancer care in the United States and worldwide.

How Is Breast Cancer Treated
Breast cancer is treated in several ways. It depends on the kind of breast cancer and how far it has spread.
Breast cancer is treated in several ways. It depends on the kind of breast cancer and how far it has spread. People with breast cancer often get more than one kind of treatment.
- Surgery. An operation where doctors cut out cancer tissue.
- Chemotherapy. Using special medicines to shrink or kill the cancer cells. The drugs can be pills you take or medicines given in your veins, or sometimes both.
- Hormonal therapy. Blocks cancer cells from getting the hormones they need to grow.
- Biological therapy. Works with your bodys immune system to help it fight cancer cells or to control side effects from other cancer treatments.
- Radiation therapy. Using high-energy rays to kill the cancer cells.
Doctors from different specialties often work together to treat breast cancer. Surgeons are doctors who perform operations. Medical oncologists are doctors who treat cancer with medicine. Radiation oncologists are doctors who treat cancer with radiation.
What’s Actually Going On With Julie’s Prison Stint
According to a new report at TMZ, however, the matriarch of the Chrisley clan is doing just fine. The prison in question in Lexington does have the medical and mental health unit, but the outlet also reports it has a regular minimum security prison, where the reality star will be housed. The outlet did not determine why the move occurred, but it does seem that Julie will not be getting treatment at this time.
For his part, her husband Todd will still be spending his prison sentence at FPC Pensacola. Chrisley may have to “scrub toilets” or do other chores during his decade-plus stay.
The Chrisleys had hoped to stave off entering prison this month, but their appeal was denied by a judge.

Considering Complementary And Alternative Methods
You may hear about alternative or complementary methods that your doctor hasnt mentioned to treat your cancer or relieve symptoms. These methods can include vitamins, herbs, and special diets, or other methods such as acupuncture or massage, to name a few.
Complementary methods refer to treatments that are used along with your regular medical care. Alternative treatments are used instead of a doctors medical treatment. Although some of these methods might be helpful in relieving symptoms or helping you feel better, many have not been proven to work. Some might even be harmful.
Be sure to talk to your cancer care team about any method you are thinking about using. They can help you learn what is known about the method, which can help you make an informed decision.

How Has A Better Understanding Of Breast Cancer Changed Treatment
Years ago, people thought about breast cancer as a single, monolithic, often life-threatening disease. The disease was subdivided into four stages: In Stage I, the tumor is small and has not spread beyond the original site with Stage II and III cancers, the tumor is larger than in Stage I and may have spread to the lymph nodes and in Stage IV, cancer has spread, or metastasized, to other parts of the body.
Outside of their stages, these cancers were thought to be the same disease, and every patient was given the same treatment.
But stage is really just the amount of cancer, Dr. Winer says. And while the stage is still part of determining treatment, its more important to take into account the type of cancer, he adds.
To that end, the types of breast cancers are categorized by their hormone receptors and whats called HER2 status.
Breast cancer cells that contain receptors for hormones like estrogen and/or progesterone are said to be hormone receptor -positive. And cancer cells that have high levels of receptors are called human epidermal growth factor receptor 2 -positive.
Cancer cells that do not contain hormones or HER2 receptors are called hormone receptor -negative or HER2-negative, respectively.
And breast cancers that do not have receptors for estrogen, progesterone, and HER2 are known as triple-negative.
