Treatment Groups

This trial involves 2 different treatments. Radiation: Single Pre-Operative Radiation Therapy is the primary treatment being studied. Participants will all receive the same treatment. There is no placebo group. The treatments being tested are in Phase 2 and have already been tested with other people.

Main TreatmentA portion of participants receive this new treatment to see if it outperforms the control.
Radiation: Single Pre-Operative Radiation Therapy
Control TreatmentAnother portion of participants receive the standard treatment to act as a baseline.

What are the signs of breast cancer?

Breast cancer has many early signs and symptoms. Common breast symptoms include lumping in the breast or a change in nipple size or shape, nipple redness, nipple discharge and itching. These symptoms are usually of mild to moderate degree. When they are of moderate to severe degree, breast cancer should be considered, as the chances that they are breast cancer increase.

What are common treatments for breast cancer?

The choice of cancer therapy for breast cancer is largely a matter of logistics; cancer treatment depends on the aggressiveness, stage, and number of malignant masses. The primary and secondary treatment options include surgery, chemotherapy, and endocrine therapy. The choice of therapy for breast cancer should be made by a multidisciplinary team including surgeons, pathologists, oncologists, radiologists, and social workers.

What is breast cancer?

The incidence of [breast cancer]( in Sweden is lower compared with that in other Western countries. It is highest among young women, especially among those who are most likely to be overweight. More women receive the opportunity to discuss their thoughts and feelings towards cancer with their doctors. Doctors perceive that most women are able to manage their disease effectively by themselves.

Anonymous Patient Answer

How many people get breast cancer a year in the United States?

About 500 women get breast cancer each year, and 1,500 more had breast cancer at the time of diagnosis. Of these, about half had been diagnosed in the previous year.

Anonymous Patient Answer

What causes breast cancer?

The main causative factors of breast cancer were obesity and family history. The most common predisposing factor for breast cancer appeared to be estrogen receptor-positive, which suggests that, in developing countries, breast cancer incidence is related to the levels of estrogen and associated with hormonal imbalances.

Anonymous Patient Answer

Can breast cancer be cured?

The role of treatment and surveillance needs to be reevaluated in prospective randomised treatments, as a consequence for a better understanding of the natural history of breast cancer.

Anonymous Patient Answer

Have there been any new discoveries for treating breast cancer?

Most of the studies concerning the treatment of breast cancer are small-scale, and often have poor study design; large-scale trials of current treatments for breast cancer should be carried out. More research in this field is urgently needed.

Anonymous Patient Answer

Is radiation: single pre-operative radiation therapy typically used in combination with any other treatments?

A radiation dose of 55 Gy given for the purpose of treatment after surgery could be considered a cost-effective alternative to standard post-operative radiotherapy, particularly for stage III disease. Further prospective multicenter trials are needed to assess the potential benefits and cost effectiveness of the treatment, especially for patients with high risk disease.

What is the primary cause of breast cancer?

In the present study we found that, compared to other countries, an early age of onset of the disease was seen in India. There appeared to be a lower incidence of the disease among all the castes as compared to other European nations. Moreover, there was a higher percentage of ER-positive and triple negative tumors among the Indian women who were younger than 35 years of age when the disease was detected.

Anonymous Patient Answer

How serious can breast cancer be?

Approximately half (49%) of a population group considered by cancer specialists to qualify as very seriously ill were identified as having breast or other cancer. There remain many unknown possibilities in terms of the spectrum of disease related to breast cancer. These may include rare instances of extremely aggressive disease. Many patients do not recall if they are under the care of an oncologist and/or radiologist. We are encouraged to consider the possibility that patients may not be optimally treated by their medical care providers. It is important to remember that in this country only 5% of physicians are women and that it is doubtful whether they may be as responsive to breast cancer patients’ needs as their male counterparts.

Anonymous Patient Answer

Have there been other clinical trials involving radiation: single pre-operative radiation therapy?

In the pre-operative radiation field of the breast for breast cancer, there is a dose-response relationship between radiation dose and both side effects from the radiotherapy and recurrence rates. However, these numbers, from the reported study in 2002, are still higher than the numbers reported from the published observational studies. Clearly, there remains a need for larger studies involving pre-operative radiotherapy. Clinical trials that look at the role of pre-operative radiotherapy in non-metastatic breast cancer should report the cumulative dose, volume of tissue being irradiated, and if it is the only radiotherapy in the disease course, treatment fields and timing.

Anonymous Patient Answer

What are the latest developments in radiation: single pre-operative radiation therapy for therapeutic use?

It may be worthwhile to consider the use of a pre-operative local dose of RT for selected patients with breast cancer for whom it might be more useful to minimize surgical trauma and morbidity to prolong survival and to minimize the potential psychological effects of the treatment.
