In September 1991, Madelaine Bullwinkel had a lump removed from her left breast. The lump was later discovered to be cancerous. She filed a claim with her insurance company seeking coverage for the lump removal and subsequent cancer treatments. The insurance company denied coverage under the pre-еxisting condition limitation in the insurance policy. The company concluded that the lump, which Madelaine first discovered in July, and which was treated by a physician on July 20, predated the July 31 effective date of the insurance policy. Made-laine and her husband filed suit under the Employee Retirement Income Security Act of 1974 (ERISA). 29 U.S.C. §§ 1001-1461. The district cоurt granted summary judgment for the insurance company. Madelaine and her husband appeal. We affirm.
I.
This case highlights the perils of changing health insurance companies during the *430 course of medical treatment. Madeline’s husband, George Bullwinkel, operates Bull-winkel Partners Limited, a law firm. For reasons not relevant to this case, George decided to offer his law firm’s employees and their dependents health insurance benefits. He negotiated a deal with New England Mutual Life Insurance Company, which agreed to begin providing health insurance on July 31, 1991. George and Madelaine enlisted under this plan.
In July 1991, Madelaine noticed a lump in her left breast. She had detected a similаr lump the previous February, but a mammogram did not reveal any abnormality. On July 20, 1991 Madelaine visited her physician, who performed an ultrasound examination. This time, he detected what he diagnosed as a cyst. He made no definite conclusion whether the cyst was cancerous or benign. He assured Madelaine, however, that more than likely the cyst was benign. But he was concerned about the possibility of cancer. He referred Madelaine to a surgeon for removal and biopsy of the cyst, telling her “Let’s be safe and take it out.”
On August 15 — two weeks after the New England Mutual insurance policy became effective — Madelaine visited the surgeon, who examined her breast. The surgeon removed the lump on September 6. Tests on the removed tissue revealed that the lump was cancerous. Since that discovery, Madelaine has had additional cancer treatment, including surgery, radiation treatment, and chemotherapy.
Madelaine sought coverage from New England Mutual for her initial surgery and subsequеnt cancer treatments. New England Mutual denied coverage, claiming that the cancer was a pre-existing condition, for which the insurance policy explicitly precluded coverage. The insurance policy contained the following “Pre-Existing Condition Limitation”:
No benefits are payable for a condition, sickness, or injury for which you or your dependent were seen, treated, diagnosed, or incurred medical expense in the six-month period just before insurance starts until the earlier of: ... for you or your dependent, the end of a period of twelve consecutive months after insurance starts.
The insurance policy defined the term “sickness” as a “bоdily disorder, disease, or mental infirmity or complication of pregnancy.”
The Bullwinkels sued New England Mutual under ERISA, seeking coverage for the surgery and cancer treatments. After a brief period of discovery, both sides moved for summary judgment. In passing on those motions, the district court reviewed the terms of the insurance policy
de novo;
nothing in the policy required deferential review of New England Mutual’s decision to deny coverage.
Cf. Firestone Tire & Rubber Co. v. Bruch,
The Bullwinkels have appealed. We must determine whether the July treatment triggered the pre-existing condition limitation in the insurance policy. If so, then New England Mutual prevails, and the post-policy treatments at issue are not covered. If not, the Bullwinkels prevail, and they are entitled to coverage.
II. Analysis
Generally, this case concerns.an insurance policy, which is a contract. Like all contracts, the writing represents an agreement between the parties. In consideration for premiums paid, New England Mutual prom *431 ised to pay health benefits to the Bullwinkels under certain terms and conditions. New England Mutual specifically refused to cover any “condition, sickness, or injury” which pre-existed the policy. 1 The Bullwinkels agreed to this provision, but they and the company disagree on its meaning.
This case is governed by ERISA, a law which requires us to apply federal cоmmon law rules of contract interpretation when interpreting the terms of an employee health insurance policy.
Hammond v. Fidelity and Guar. Life Ins. Co.,
The first portion of the pre-existing condition limitation succinctly states the exclusion: “No benefits are payable for a condition, sickness, or injury for which you or your dependent were seen, treated, diagnosed, or incurred medical expense in the six-month period just before insurance starts....” Both sides agree that the breast lump was a condition which was diagnosed and treated in July, before the effective date of the policy. Therefore, both sides essentially concede that thе post-policy treatment of the lump— the August 15 visit to the surgeon and the September 6 lump removal — is not covered under the policy. This appeal, then, focuses on the cancer treatments which took place after the lump was removed. The Bullwink-els argue that cancer was never diagnosed in July, and therefore that Mаdelaine was never “seen, treated, diagnosed,” nor did she incur medical expenses for cancer in July. In short, they argue that while the lump may have been a pre-existing condition under the policy, the cancer was not since it was not actually diagnosed. New England Mutual does not make the same distinction between the lump and thе cancer. According to New England Mutual, the September biopsy conclusively established that the lump was cancerous. Therefore, any treatment for the lump in July was actually treatment for cancer, and cancer was a pre-existing condition for which coverage was excluded.
The Bullwinkels cite a number of cases to support the distinction they draw between the lump and the cancer. They present their argument in this respect as follows:
[Ojther courts have recognized this principle: having a slight spine curvature is not the same as having scoliosis. Rivera v. Benefit Trust Life Insurance Co.,921 F.2d 692 (7th Cir.1991). Having bloody stools is not. equivalent to having rectal cancer. Holub v. Holy Family Society,164 Ill. App.3d 970 ,115 Ill.Dec. 894 ,518 N.E.2d 419 (1st Dist.1987). An inverted nipple is not already а breast cancer. Bonura v. United Bankers Life Ins. Co.,552 So.2d 1248 (La.1989). A mole on a doctor’s back is not to be presumed a malignant cancer. Hood v. Security Insurance Co. of New Haven, [247 S.C. 71 ],145 S.E.2d 526 (S.C. 1965). Being diagnosed with pulmonary hypertension is not equivalent to having an atrial septal defect. Ross v. Western Fidelity Ins. Co.,872 F.2d 665 (5th Cir.1989). By way of contrast, [see ] Kirk v. Provident Life & Acc. Ins. Co.,942 F.2d 504 (8th Cir.1991)....
Unfortunately, the eases the Bullwinkels cite are not very helpful. Most did not involve interpretation of a pre-existing condition limitatiоn in an insurance policy. None addressed language closely similar to the lan
*432
guage we have been asked to interpret in this case. Indeed,
Rivera,
Only
Kirk,
The court was asked to interpret a preexisting condition exclusion which provided that “[n]o benefits [are] payable for expenses due to any Injury or Illness beginning before the effective date of coverage.” That case, like this one, was governed by ERISA. The court determined that Kirk was not covered for the heart condition, because it pre-dated the policy. The court was unpersuaded by the fact that the condition was not accurately diagnosed until after the policy became effective. The court also separated its decision from the type of case where “‘the insured has some supposedly trivial infirmity or abnormality when the policy took effect. Later on, however, the condition changed for the worse and for the first time either actually became, or became diagnosable as, a sickness or disease falling within the coverage of the policy.’”
Kirk,
If we were to base our decision on Kirk, we would аffirm the district court’s denial of coverage in this case. As in Kirk, the condition in this case was not fully diagnosed until after the insurance became effective. And as in Kirk, the symptoms which Madelaine exhibited were not trivial and inconclusive— like a cough or a rash which might imply any of a variety of maladies, or none at all. The breast lump was anything but trivial; in September it was determined to be cancer.
Though instructive, Kirk is not the last word in this ease. The insurance policy language which the court interpreted in Kirk differs significantly from the language in the policy before us. Therefore, our analysis returns to the policy language which this case presents. Is a malignant breast lump— discovered before the effective date of an insurance policy but not definitely diagnosed as cancer until after coverage commenced — a “condition, sickness, or injury” for which Ma-delaine was “seen, treated, diagnosed, or incurred medical expenses” in July? Certainly, a malignant breast tumor is a “condition” and a “sickness.” True, Madelaine was never “seen, treated, diagnosed” specifically for breast cancer in July, nor did she incur medical expenses specifically for breast cancer in July. But she was “seen, treated, diagnosed” and she did incur medical expenses for a breast lump in July. The lump was discovered in September to be cancerous. We may infer frоm this fact that the lump was also cancerous in July. So, even though Madelaine did not know the lump was cancerous in July, her visit with the doctor in that month concerning the lump actually concerned cancer. It follows that Madelaine was “seen” and “treated” and incurred medical expenses for her cancer in July. Therefore, any post-policy treatment concerning the same condition is not covered.
Ultimately, the Bullwinkels rest their entire appeal on one argument. They claim that a court cannot conclude on summary judgment that a lump discovered to be can- *433 cereras in September was also cancerous in July. They argue that this cоnclusion can only be made by a fact-finder. They request a remand to give the fact-finder an opportunity to consider the competing inferences. At oral argument, the Bullwinkels’ attorney conceded that if the lump was cancerous in July, then the pre-existing condition limitation would preclude coverage. He made this conсession during questioning by the court:
COURT: But what fact can be revealed [on remand]?
ATTORNEY: Did she have breast cancer for which she was treated [in July]?
COURT: Suppose every doctor that knows anything about cancer says that this was there for a year?
ATTORNEY: But no doctor said that.
COURT: But suppose they do. Do you lose?
ATTORNEY: We lose.
The problem with granting a remand is that the record does not present competing inferences. The only reasonable inference which the rеcord in this case allows is that the lump discovered to be cancerous in September was also cancerous in July. See
Donohue v. Consolidated Operating & Production Corp.,
Obviously, this ease is not an authorization fоr summary judgment in all future cases dealing with pre-existing condition limitations. Several attributes make this case unique. First, the lump discovered in July was not a trivial and inconclusive symptom.

III. Conclusion
For the foregoing reasons we
AFFIRM.
Notes
. Under the terms of the policy, the pre-existing condition provision limited coverage only for one year after the insurance became effective. The treatments at issue in this case all took place in that year. The parties have not asked us to determine whether Madelaine would be entitled to coverage for treatments occurring after the one year period.
